CVE-2021-36126 1 Mediawiki 1 Mediawiki 2024-11-21 9.8 Critical
An issue was discovered in the AbuseFilter extension in MediaWiki through 1.36. If the MediaWiki:Abusefilter-blocker message is invalid within the content language, the filter user falls back to the English version, but that English version could also be invalid on a wiki. This would result in a fatal error, and potentially fail to block or restrict a potentially nefarious user.
CVE-2021-36125 1 Mediawiki 1 Mediawiki 2024-11-21 7.5 High

CVE-2021-31553 1 Mediawiki 1 Mediawiki 2024-11-21 6.5 Medium
An issue was discovered in the CheckUser extension for MediaWiki through 1.35.2. MediaWiki usernames with trailing whitespace could be stored in the cu_log database table such that denial of service occurred for certain CheckUser extension pages and functionality.

CVE-2021-31552 1 Mediawiki 1 Mediawiki 2024-11-21 5.4 Medium
An issue was discovered in the AbuseFilter extension for MediaWiki through 1.35.2. It incorrectly executed certain rules related to blocking accounts after account creation. Such rules would allow for user accounts to be created while blocking only the IP address used to create an account (and not the user account itself). Such rules could also be used by a nefarious, unprivileged user to catalog and enumerate any number of IP addresses related to these account creations.
