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":["CVE-2020-25814","GHSA-4vr7-m8p8-434h"],"modified":"2025-04-03T14:40:37.652Z","published":"2024-03-06T11:14:01.094Z","database_specific":{"cpes":["cpe:2.3:a:mediawiki:mediawiki:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6/"},{"type":"WEB","url":"https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048480.html"},{"type":"WEB","url":"https://lists.wikimedia.org/pipermail/mediawiki-l/2020-September/048488.html"},{"type":"WEB","url":"https://www.mediawiki.org/wiki/ResourceLoader/Core_modules#mediawiki.jqueryMsg"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-25814"}],"affected":[{"package":{"name":"mediawiki","ecosystem":"Bitnami","purl":"pkg:bitnami/mediawiki"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.31.10"},{"introduced":"1.32.0"},{"fixed":"1.34.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mediawiki/BIT-mediawiki-2020-25814.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}],"schema_version":"1.7.3"}
