CVE-2020-26137 4 Canonical, Debian, Oracle and 1 more 4 Ubuntu Linux, Debian Linux, Zfs Storage Appliance Kit and 1 more 2022-07-25 6.4 MEDIUM 6.5 MEDIUM
urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this is similar to CVE-2020-26116.
CVE-2021-28363 3 Fedoraproject, Oracle, Python 3 Fedora, Peoplesoft Enterprise Peopletools, Urllib3 2021-12-08 6.4 MEDIUM 6.5 MEDIUM
The urllib3 library 1.26.x before 1.26.4 for Python omits SSL certificate validation in some cases involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given via proxy_config) doesn't verify the hostname of the certificate. This means certificates for different servers that still validate properly with the default urllib3 SSLContext will be silently accepted.
CVE-2019-11236 1 Python 1 Urllib3 2021-06-15 4.3 MEDIUM 6.1 MEDIUM
In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.
