|---|---|---|---|---|---|
| CVE-2021-29958 | 1 Mozilla | 1 Firefox | 2022-07-12 | 4.3 MEDIUM | 4.3 MEDIUM |
| When a download was initiated, the client did not check whether it was in normal or private browsing mode, which led to private mode cookies being shared in normal browsing mode. This vulnerability affects Firefox for iOS < 34. | |||||
| CVE-2021-38502 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2022-07-12 | 4.3 MEDIUM | 5.9 MEDIUM |
| Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected authentication method was configured, the MITM could obtain the authentication credentials, too. This vulnerability affects Thunderbird < 91.2. | |||||
| CVE-2021-29951 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2022-07-12 | 6.4 MEDIUM | 6.5 MEDIUM |
| The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network, grants normal remote users access to start or stop the service. This could be used to prevent the browser update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack surface in the maintenance service. *Note: This issue only affected Windows operating systems older than Win 10 build 1709. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.10.1, Firefox < 87, and Firefox ESR < 78.10.1. | |||||
| CVE-2021-23985 | 1 Mozilla | 1 Firefox | 2022-07-12 | 4.3 MEDIUM | 6.5 MEDIUM |
| If an attacker is able to alter specific about:config values (for example malware running on the user's computer), the Devtools remote debugging feature could have been enabled in a way that was unnoticable to the user. This would have allowed a remote attacker (able to make a direct network connection to the victim) to monitor the user's browsing activity and (plaintext) network traffic. This was addressed by providing a visual cue when Devtools has an open network socket. This vulnerability affects Firefox < 87. | |||||
| CVE-2021-29959 | 1 Mozilla | 1 Firefox | 2022-07-12 | 4.3 MEDIUM | 4.3 MEDIUM |
| When a user has already allowed a website to access microphone and camera, disabling camera sharing would not fully prevent the website from re-enabling it without an additional prompt. This was only possible if the website kept recording with the microphone until re-enabling the camera. This vulnerability affects Firefox < 89. | |||||
| CVE-2021-43540 | 1 Mozilla | 1 Firefox | 2022-07-12 | 4.3 MEDIUM | 6.5 MEDIUM |
| WebExtensions with the correct permissions were able to create and install ServiceWorkers for third-party websites that would not have been uninstalled with the extension. This vulnerability affects Firefox < 95. | |||||
| CVE-2021-23977 | 1 Mozilla | 1 Firefox | 2022-05-27 | 2.6 LOW | 5.3 MEDIUM |
| Firefox for Android suffered from a time-of-check-time-of-use vulnerability that allowed a malicious application to read sensitive data from application directories. Note: This issue is only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 86. | |||||
| CVE-2021-23969 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-05-27 | 4.3 MEDIUM | 4.3 MEDIUM |
| As specified in the W3C Content Security Policy draft, when creating a violation report, "User agents need to ensure that the source file is the URL requested by the page, pre-redirects. If that’s not possible, user agents need to strip the URL down to an origin to avoid unintentional leakage." Under certain types of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. | |||||
| CVE-2021-23975 | 1 Mozilla | 1 Firefox | 2022-05-27 | 4.3 MEDIUM | 6.5 MEDIUM |
| The developer page about:memory has a Measure function for exploring what object types the browser has allocated and their sizes. When this function was invoked we incorrectly called the sizeof function, instead of using the API method that checks for invalid pointers. This vulnerability affects Firefox < 86. | |||||
| CVE-2021-23970 | 1 Mozilla | 1 Firefox | 2022-05-27 | 4.3 MEDIUM | 6.5 MEDIUM |
| Context-specific code was included in a shared jump table; resulting in assertions being triggered in multithreaded wasm code. This vulnerability affects Firefox < 86. | |||||
| CVE-2021-23971 | 1 Mozilla | 1 Firefox | 2022-05-27 | 4.3 MEDIUM | 6.5 MEDIUM |
| When processing a redirect with a conflicting Referrer-Policy, Firefox would have adopted the redirect's Referrer-Policy. This would have potentially resulted in more information than intended by the original origin being provided to the destination of the redirect. This vulnerability affects Firefox < 86. | |||||
| CVE-2021-23973 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-05-27 | 4.3 MEDIUM | 6.5 MEDIUM |
| When trying to load a cross-origin resource in an audio/video context a decoding error may have resulted, and the content of that error may have revealed information about the resource. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. | |||||
| CVE-2021-23968 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-05-27 | 4.3 MEDIUM | 4.3 MEDIUM |
| If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. This could be used to leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. | |||||
| CVE-2021-23974 | 1 Mozilla | 1 Firefox | 2022-05-23 | 4.3 MEDIUM | 6.1 MEDIUM |
| The DOMParser API did not properly process '<noscript>' elements for escaping. This could be used as an mXSS vector to bypass an HTML Sanitizer. This vulnerability affects Firefox < 86. | |||||
| CVE-2019-7317 | 11 Canonical, Debian, Hp and 8 more | 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more | 2022-05-23 | 2.6 LOW | 5.3 MEDIUM |
| png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute. | |||||
| CVE-2021-4138 | 1 Mozilla | 1 Geckodriver | 2022-05-11 | 5.0 MEDIUM | 5.3 MEDIUM |
| Improved Host header checks to reject requests not sent to a well-known local hostname or IP, or the server-specified hostname. | |||||
| CVE-2021-23983 | 1 Mozilla | 1 Firefox | 2022-05-03 | 4.3 MEDIUM | 6.5 MEDIUM |
| By causing a transition on a parent node by removing a CSS rule, an invalid property for a marker could have been applied, resulting in memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 87. | |||||
| CVE-2020-12405 | 2 Canonical, Mozilla | 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more | 2022-05-03 | 2.6 LOW | 5.3 MEDIUM |

| A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. | |||||
| CVE-2020-12392 | 2 Canonical, Mozilla | 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more | 2022-04-26 | 2.1 LOW | 5.5 MEDIUM |
| The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. | |||||
| CVE-2021-43545 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-28 | 4.3 MEDIUM | 6.5 MEDIUM |
| Using the Location API in a loop could have caused severe application hangs and crashes. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-38506 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-28 | 4.3 MEDIUM | 4.3 MEDIUM |
| Through a series of navigations, Firefox could have entered fullscreen mode without notification or warning to the user. This could lead to spoofing attacks on the browser UI including phishing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38507 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |
| The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded to TLS while retaining the visual properties of an HTTP connection, including being same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port 8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-38509 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 4.3 MEDIUM |
| Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-43538 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 4.3 MEDIUM |
| By misusing a race in our notification code, an attacker could have forcefully hidden the notification for pages that had received full screen and pointer lock access, which could have been used for spoofing attacks. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-43542 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |
| Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages for loading external protocols. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-43546 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 4.3 MEDIUM |
| It was possible to recreate previous cursor spoofing attacks against users with a zoomed native cursor. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-29982 | 1 Mozilla | 2 Firefox, Thunderbird | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |

| CVE-2021-29987 | 2 Linux, Mozilla | 3 Linux Kernel, Firefox, Thunderbird | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |
| After requesting multiple permissions, and closing the first permission panel, subsequent permission panels will be displayed in a different position but still record a click in the default location, making it possible to trick a user into accepting a permission they did not want to. *This bug only affects Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and Thunderbird < 91. | |||||
| CVE-2021-38508 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 4.3 MEDIUM |
| By displaying a form validity message in the correct location at the same time as a permission prompt (such as for geolocation), the validity message could have obscured the prompt, resulting in the user potentially being tricked into granting the permission. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-29975 | 1 Mozilla | 1 Firefox | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |
| Through a series of DOM manipulations, a message, over which the attacker had control of the text but not HTML or formatting, could be overlaid on top of another domain (with the new domain correctly shown in the address bar) resulting in possible user confusion. This vulnerability affects Firefox < 90. | |||||
| CVE-2021-29974 | 1 Mozilla | 1 Firefox | 2022-02-22 | 2.6 LOW | 4.3 MEDIUM |
| When network partitioning was enabled, e.g. as a result of Enhanced Tracking Protection settings, a TLS error page would allow the user to override an error on a domain which had specified HTTP Strict Transport Security (which implies that the error should not be override-able.) This issue did not affect the network connections, and they were correctly upgraded to HTTPS automatically. This vulnerability affects Firefox < 90. | |||||
| CVE-2021-43543 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 6.1 MEDIUM |
| Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by embedding additional content. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-43541 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |
| When invoking protocol handlers for external protocols, a supplied parameter URL containing spaces was not properly escaped. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. | |||||
| CVE-2021-38491 | 1 Mozilla | 1 Firefox | 2022-02-22 | 4.3 MEDIUM | 6.5 MEDIUM |

| NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9. | |||||
| CVE-2020-12402 | 4 Debian, Fedoraproject, Mozilla and 1 more | 4 Debian Linux, Fedora, Firefox and 1 more | 2022-01-04 | 1.2 LOW | 4.4 MEDIUM |
| During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78. | |||||
| CVE-2021-43528 | 1 Mozilla | 1 Thunderbird | 2022-01-04 | 4.3 MEDIUM | 6.5 MEDIUM |
| Thunderbird unexpectedly enabled JavaScript in the composition area. The JavaScript execution context was limited to this area and did not receive chrome-level privileges, but could be used as a stepping stone to further an attack with other vulnerabilities. This vulnerability affects Thunderbird < 91.4.0. | |||||
| CVE-2019-17021 | 3 Microsoft, Mozilla, Opensuse | 4 Windows, Firefox, Firefox Esr and 1 more | 2022-01-01 | 2.6 LOW | 5.3 MEDIUM |
| During the initialization of a new content process, a race condition occurs that can allow a content process to disclose heap addresses from the parent process. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. | |||||
| CVE-2020-6792 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Thunderbird | 2022-01-01 | 4.3 MEDIUM | 4.3 MEDIUM |
| When deriving an identifier for an email message, uninitialized memory was used in addition to the message contents. This vulnerability affects Thunderbird < 68.5. | |||||
| CVE-2020-6794 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Thunderbird | 2022-01-01 | 4.3 MEDIUM | 6.5 MEDIUM |
| If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5. | |||||
| CVE-2020-6793 | 1 Mozilla | 1 Thunderbird | 2022-01-01 | 4.3 MEDIUM | 6.5 MEDIUM |
| When processing an email message with an ill-formed envelope, Thunderbird could read data from a random memory location. This vulnerability affects Thunderbird < 68.5. | |||||
| CVE-2021-38505 | 2 Microsoft, Mozilla | 4 Windows 10, Firefox, Firefox Esr and 1 more | 2021-12-10 | 4.3 MEDIUM | 6.5 MEDIUM |
| Microsoft introduced a new feature in Windows 10 known as Cloud Clipboard which, if enabled, will record data copied to the clipboard to the cloud, and make it available on other computers in certain scenarios. Applications that wish to prevent copied data from being recorded in Cloud History must use specific clipboard formats; and Firefox before versions 94 and ESR 91.3 did not implement them. This could have caused sensitive data to be recorded to a user's Microsoft account. *This bug only affects Firefox for Windows 10+ with Cloud Clipboard enabled. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | |||||
| CVE-2021-43530 | 2 Google, Mozilla | 2 Android, Firefox | 2021-12-10 | 4.3 MEDIUM | 6.1 MEDIUM |
| A Universal XSS vulnerability was present in Firefox for Android resulting from improper sanitization when processing a URL scanned from a QR code. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43531 | 1 Mozilla | 1 Firefox | 2021-12-10 | 4.3 MEDIUM | 4.3 MEDIUM |
| When a user loaded a Web Extensions context menu, the Web Extension could access the post-redirect URL of the element clicked. If the Web Extension lacked the WebRequest permission for the hosts involved in the redirect, this would be a same-origin-violation leaking data the Web Extension should have access to. This was fixed to provide the pre-redirect URL. This is related to CVE-2021-43532 but in the context of Web Extensions. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43532 | 1 Mozilla | 1 Firefox | 2021-12-10 | 5.8 MEDIUM | 6.1 MEDIUM |
| The 'Copy Image Link' context menu action would copy the final image URL after redirects. By embedding an image that triggered authentication flows - in conjunction with a Content Security Policy that stopped a redirection chain in the middle - the final image URL could be one that contained an authentication token used to takeover a user account. If a website tricked a user into copy and pasting the image link back to the page, the page would be able to steal the authentication tokens. This was fixed by making the action return the original URL, before any redirects. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43533 | 1 Mozilla | 1 Firefox | 2021-12-10 | 4.3 MEDIUM | 4.3 MEDIUM |
| When parsing internationalized domain names, high bits of the characters in the URLs were sometimes stripped, resulting in inconsistencies that could lead to user confusion or attacks such as phishing. This vulnerability affects Firefox < 94. | |||||
| CVE-2021-43544 | 2 Google, Mozilla | 2 Android, Firefox | 2021-12-10 | 4.3 MEDIUM | 6.1 MEDIUM |
| When receiving a URL through a SEND intent, Firefox would have searched for the text, but subsequent usages of the address bar might have caused the URL to load unintentionally, which could lead to XSS and spoofing attacks. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 95. | |||||
| CVE-2021-38492 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-11-04 | 4.3 MEDIUM | 6.5 MEDIUM |
| When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. *This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 92, Thunderbird < 91.1, Thunderbird < 78.14, Firefox ESR < 78.14, and Firefox ESR < 91.1. | |||||
| CVE-2021-38497 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-11-04 | 4.3 MEDIUM | 6.5 MEDIUM |
| Through use of reportValidity() and window.open(), a plain-text validation message could have been overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. | |||||
