| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2024-34502 | CRITICAL | 9.8 | May 5, 2024 | An issue was discovered in WikibaseLexeme in MediaWiki before 1.39.6, 1.40.x before 1.40.2, and 1.41.x before 1.41.1. Loading Special:MergeLexemes will (attempt to) make an edit that merges the from-id to the to-id, even if the request was not a POST request, and even if it does not contain an edit token. |
| CVE-2024-40597 | HIGH | 7.5 | Jul 7, 2024 | An issue was discovered in the CheckUser extension for MediaWiki through 1.42.1. It can expose suppressed information for log events. (The log_deleted attribute is not respected.) |
| CVE-2024-34506 | HIGH | 7.5 | May 5, 2024 | An issue was discovered in includes/specials/SpecialMovePage.php in MediaWiki before 1.39.7, 1.40.x before 1.40.3, and 1.41.x before 1.41.1. If a user with the necessary rights to move the page opens Special:MovePage for a page with tens of thousands of subpages, then the page will exceed the maximum request time, leading to a denial of service. |
| CVE-2023-45371 | HIGH | 7.5 | Oct 9, 2023 | An issue was discovered in the Wikibase extension for MediaWiki before 1.35.12, 1.36.x through 1.39.x before 1.39.5, and 1.40.x before 1.40.1. There is no rate limit for merging items. |
| CVE-2023-45363 | HIGH | 7.5 | Oct 9, 2023 | An issue was discovered in ApiPageSet.php in MediaWiki before 1.35.12, 1.36.x through 1.39.x before 1.39.5, and 1.40.x before 1.40.1. It allows attackers to cause a denial of service (unbounded loop and RequestTimeoutException) when querying pages redirected to other variants with redirects and converttitles set. |
| CVE-2020-12051 | HIGH | 7.5 | Apr 21, 2020 | 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-2024-34507 | HIGH | 7.4 | May 5, 2024 | An issue was discovered in includes/CommentFormatter/CommentParser.php in MediaWiki before 1.39.7, 1.40.x before 1.40.3, and 1.41.x before 1.41.1.

| CVE-2023-3550 | HIGH | 7.3 | Sep 25, 2023 | Mediawiki v1.40.0 does not validate namespaces used in XML files. Therefore, if the instance administrator allows XML file uploads, a remote attacker with a low-privileged user account can use this exploit to become an administrator by sending a malicious link to the instance administrator. |

A user can use a rest.php/checkuser/v0/useragent-clienthints/revision/ URL to store an arbitrary number of rows in cu_useragent_clienthints, leading to a denial of service. |
| CVE-2024-34500 | MEDIUM | 6.1 | May 5, 2024 | An issue was discovered in the UnlinkedWikibase extension in MediaWiki before 1.39.6, 1.40.x before 1.40.2, and 1.41.x before 1.41.1.
