{"id":"BIT-mediawiki-2020-26121","details":"An issue was discovered in the FileImporter extension for MediaWiki before 1.34.4. An attacker can import a file even when the target page is protected against \"page creation\" and the attacker should not be able to create it. This occurs because of a mishandled distinction between an upload restriction and a create restriction. An attacker cannot leverage this to overwrite anything, but can leverage this to force a wiki to have a page with a disallowed title.","aliases":["CVE-2020-26121"],"modified":"2025-04-03T14:40:37.652Z","published":"2024-03-06T11:13:50.275Z","database_specific":{"cpes":["cpe:2.3:a:mediawiki:mediawiki:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://commons.wikimedia.org/w/index.php?oldid=454609892#File:Wiki.png"},{"type":"WEB","url":"https://gerrit.wikimedia.org/r/q/Ib852a96afc4dca10516d0510e69c10f9892b351b"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RTTPZ7XMDS66I442OLLHXBDNP2LCBJU6/"},{"type":"WEB","url":"https://phabricator.wikimedia.org/T262628"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-26121"}],"affected":[{"package":{"name":"mediawiki","ecosystem":"Bitnami","purl":"pkg:bitnami/mediawiki"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.34.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mediawiki/BIT-mediawiki-2020-26121.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}],"schema_version":"1.7.3"}
