{"id":"BIT-mediawiki-2021-36126","details":"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.","aliases":["CVE-2021-36126"],"modified":"2025-04-03T14:40:37.652Z","published":"2024-03-06T11:11:35.468Z","database_specific":{"cpes":["cpe:2.3:a:mediawiki:mediawiki:*:*:*:*:*:*:*:*"],"severity":"Critical"},"references":[{"type":"WEB","url":"https://gerrit.wikimedia.org/r/q/I9e9f44b7663e810de70fb9ac7f6760f83dd4895b"},{"type":"WEB","url":"https://phabricator.wikimedia.org/T284364"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-36126"}],"affected":[{"package":{"name":"mediawiki","ecosystem":"Bitnami","purl":"pkg:bitnami/mediawiki"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.36.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mediawiki/BIT-mediawiki-2021-36126.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.7.3"}
