{"id":"CVE-2020-25814","details":"In MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4, XSS related to jQuery can occur. The attacker creates a message with [javascript:payload xss] and turns it into a jQuery object with mw.message().parse(). The expected result is that the jQuery object does not contain an \u003ca\u003e tag (or it does not have a href attribute, or it's empty, etc.). The actual result is that the object contains an \u003ca href =\"javascript... that executes when clicked.","aliases":["BIT-mediawiki-2020-25814","GHSA-4vr7-m8p8-434h"],"modified":"2026-04-09T07:03:47.724090Z","published":"2020-09-27T21:15:12.687Z","related":["MGASA-2020-0381"],"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6/"},{"type":"ADVISORY","url":"https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048480.html"},{"type":"ADVISORY","url":"https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048488.html"},{"type":"ADVISORY","url":"https://www.mediawiki.org/wiki/ResourceLoader/Core_modules#mediawiki.jqueryMsg"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wikimedia/mediawiki","events":[{"introduced":"0"},{"fixed":"0fa7240e6a81be24dc0eb3c250ec2a25a2099faa"},{"introduced":"0fbb878ef366477535a709b0c2564bdcf4b176d1"},{"fixed":"e34e7f20b51ed7514ba6de8d8a390363ade2237f"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.31.10"},{"introduced":"1.32.0"},{"fixed":"1.34.4"}]}}],"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","1.31.2","1.31.3","1.31.4","1.31.5","1.31.6","1.31.7","1.31.8","1.31.9","1.34.0","1.34.0-rc.0","1.34.0-rc.1","1.34.1","1.34.2","1.34.3","1.5.0alpha1","1.5.0alpha2","1.5.0beta1","1.5.0beta2","1.5.0beta3","1.5.0beta4","1.6.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-25814.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"33"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
