{"id":"GHSA-4vr7-m8p8-434h","aliases":["BIT-mediawiki-2020-25814","CVE-2020-25814"],"title":"MediaWiki Cross-site Scripting (XSS) vulnerability","description":"In MediaWiki before 1.31.9 and 1.32.x through 1.34.x before 1.34.3, 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 <a> tag (or it does not have a href attribute, or it's empty, etc.). The actual result is that the object contains an <a href =\"javascript... that executes when clicked.","severity":"medium","score":6.1,"published":"2022-05-24T17:29:42.000Z","modified":"2024-05-19T02:24:07.692Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"mediawiki/core","ranges":[{"events":[{"introduced":"1.31.0"},{"fixed":"1.31.9"}],"type":"ECOSYSTEM"}],"versions":["1.31.0","1.31.1","1.31.2","1.31.3","1.31.4","1.31.5","1.31.6","1.31.7","1.31.8"],"fixed":["1.31.9"]},{"ecosystem":"Packagist","name":"mediawiki/core","ranges":[{"events":[{"introduced":"1.32.0"},{"fixed":"1.34.3"}],"type":"ECOSYSTEM"}],"versions":["1.32.0","1.32.1","1.32.2","1.32.3","1.32.4","1.32.5","1.32.6","1.33.0","1.33.0-rc.0","1.33.1","1.33.2","1.33.3","1.33.4","1.34.0","1.34.0-rc.0","1.34.0-rc.1","1.34.1","1.34.2"],"fixed":["1.34.3"]},{"ecosystem":"Packagist","name":"mediawiki/core","ranges":[{"events":[{"introduced":"1.35.0-rc.0"},{"fixed":"1.35.0"}],"type":"ECOSYSTEM"}],"versions":["1.35.0-rc.0","1.35.0-rc.1","1.35.0-rc.2","1.35.0-rc.3"],"fixed":["1.35.0"]}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2020-25814","https://github.com/FriendsOfPHP/security-advisories/blob/master/mediawiki/core/CVE-2020-25814.yaml","https://github.com/wikimedia/mediawiki","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6","https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048480.html","https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048488.html","https://phabricator.wikimedia.org/T86738","https://www.mediawiki.org/wiki/ResourceLoader/Core_modules#mediawiki.jqueryMsg"],"sources":[{"name":"OSV","id":"GHSA-4vr7-m8p8-434h","modified":"2024-05-19T02:24:07.692788Z","url":"https://osv.dev/vulnerability/GHSA-4vr7-m8p8-434h"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1}]}
