{"id":"CVE-2021-35197","details":"In MediaWiki before 1.31.15, 1.32.x through 1.35.x before 1.35.3, and 1.36.x before 1.36.1, bots have certain unintended API access. When a bot account has a \"sitewide block\" applied, it is able to still \"purge\" pages through the MediaWiki Action API (which a \"sitewide block\" should have prevented).","aliases":["BIT-mediawiki-2021-35197"],"modified":"2026-04-16T04:43:25.626573922Z","published":"2021-07-02T13:15:07.727Z","references":[{"type":"WEB","url":"https://lists.wikimedia.org/hyperkitty/list/mediawiki-announce%40lists.wikimedia.org/thread/YR3X4L2CPSEJVSY543AWEO65TD6APXHP/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CJDYJQWT43GBD6GNQ4OW7JOZ6WQ6DZTN/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MDBPECBWN6LWNSWIQMVXK6PP4YFEUYHA/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QNEAI2T3Y65I55ZB6UE6RMC662RZTGRX/"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202107-40"},{"type":"ADVISORY","url":"https://www.debian.org/security/2021/dsa-4979"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2021/10/msg00003.html"},{"type":"EVIDENCE","url":"https://phabricator.wikimedia.org/T280226"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wikimedia/mediawiki","events":[{"introduced":"0"},{"fixed":"db844fb107e8a74e0c8a7455012a20f977fa790d"},{"introduced":"0fbb878ef366477535a709b0c2564bdcf4b176d1"},{"fixed":"923676858a9521c96b7051641010d920796bb408"},{"introduced":"bc542ec6d8573dfb906b468901799e0017875f1e"},{"fixed":"b6cf6b337262ed84b76e96ed0f7ccbb702a46e9c"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.31.15"},{"introduced":"1.32.0"},{"fixed":"1.35.3"},{"introduced":"1.36.0"},{"fixed":"1.36.1"}]}}],"versions":["1.1.0","1.3.0beta1","1.31.0","1.31.0-rc.0","1.31.0-rc.1","1.31.0-rc.2","1.31.1","1.31.10","1.31.11","1.31.12","1.31.13","1.31.14","1.31.2","1.31.3","1.31.4","1.31.5","1.31.6","1.31.7","1.31.8","1.31.9","1.35.0","1.35.0-rc.0","1.35.0-rc.1","1.35.0-rc.2","1.35.0-rc.3","1.35.1","1.35.2","1.36.0","1.5.0alpha1","1.5.0alpha2","1.5.0beta1","1.5.0beta2","1.5.0beta3","1.5.0beta4","1.6.0"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]},{"events":[{"introduced":"0"},{"last_affected":"11.0"}]},{"events":[{"introduced":"0"},{"last_affected":"33"}]},{"events":[{"introduced":"0"},{"last_affected":"34"}]},{"events":[{"introduced":"0"},{"last_affected":"35"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-35197.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
