| An information leak was discovered in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. Handling of actor ID does not necessarily use the correct database or correct wiki. | |||||
| CVE-2020-26121 | 2 Fedoraproject, Mediawiki | 2 Fedora, Mediawiki | 2022-01-06 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the FileImporter extension for MediaWiki before 1.34.4. An attacker can import a file even when the target page is protected against "page creation" and the attacker should not be able to create it. This occurs because of a mishandled distinction between an upload restriction and a create restriction. An attacker cannot leverage this to overwrite anything, but can leverage this to force a wiki to have a page with a disallowed title. | |||||
| CVE-2020-25827 | 2 Fedoraproject, Mediawiki | 2 Fedora, Mediawiki | 2022-01-01 | 5.0 MEDIUM | 7.5 HIGH |

(The right column with the changeable groups is not affected and is escaped correctly.) | |||||
| CVE-2019-16528 | 1 Mediawiki | 1 Abusefilter | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the AbuseFilter extension for MediaWiki. includes/special/SpecialAbuseLog.php allows attackers to obtain sensitive information, such as deleted/suppressed usernames and summaries, from AbuseLog revision data. This affects REL1_32 and REL1_33. | |||||
| CVE-2020-12051 | 1 Mediawiki | 1 Mediawiki | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| The CentralAuth extension through REL1_34 for MediaWiki allows remote attackers to obtain sensitive hidden account information via an api.php?action=query&meta=globaluserinfo&guiuser= request. In other words, the information can be retrieved via the action API even though access would be denied when simply visiting wiki/Special:CentralAuth in a web browser. | |||||
| CVE-2020-35625 | 1 Mediawiki | 1 Mediawiki | 2021-07-21 | 6.5 MEDIUM | 8.8 HIGH |
| An issue was discovered in the Widgets extension for MediaWiki through 1.35.1. Any user with the ability to edit pages within the Widgets namespace could call any static function within any class (defined within PHP or MediaWiki) via a crafted HTML comment, related to a Smarty template.
