{"id":"CVE-2026-126561","summary":"Semantic MediaWiki 2.5.0 before 7.4.1 Missing Authorization via Is edit protected Annotation","details":"Semantic MediaWiki 2.5.0 before 7.4.1 contains a missing authorization vulnerability that allows editors without the edit-protection right to lock pages by adding an Is edit protected annotation. Attackers can add [[Is edit protected::true]] to pages or #set it in widely transcluded templates, so the TitleQuickPermissions hook blocks other editors and administrators from editing, moving or deleting them indefinitely.","aliases":["GHSA-9w3p-9m8x-j2mw"],"modified":"2026-11-12T02:48:36.053825691Z","published":"2026-11-11T02:35:57.916Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126561.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/126xxx/CVE-2026-126561.json"},{"type":"ADVISORY","url":"https://github.com/SemanticMediaWiki/SemanticMediaWiki/releases/tag/7.4.1"},{"type":"ADVISORY","url":"https://github.com/SemanticMediaWiki/SemanticMediaWiki/security/advisories/GHSA-9w3p-9m8x-j2mw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-126561"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/semantic-mediawiki-2.5.0-before-7.4.1-missing-authorization-via-is-edit-protected-annotation"},{"type":"FIX","url":"https://github.com/SemanticMediaWiki/SemanticMediaWiki/commit/ca81329c74aa64077f367e02ad00c079458ef10a"},{"type":"PACKAGE","url":"https://github.com/SemanticMediaWiki/SemanticMediaWiki"},{"type":"ARTICLE","url":"https://github.com/SemanticMediaWiki/SemanticMediaWiki/blob/7.4.0/src/Protection/ProtectionValidator.php#L293-L311"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/semanticmediawiki/semanticmediawiki","events":[{"introduced":"dbbf3d1e465f95c912da2ef421db729ad90f993e"},{"fixed":"bcc3cbf4884f0474232a68d3eff060f93a506379"},{"fixed":"ca81329c74aa64077f367e02ad00c079458ef10a"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"2.5.0"},{"fixed":"7.4.1"}],"source":"AFFECTED_FIELD"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"ca81329c74aa64077f367e02ad00c079458ef10a"}]},{"original_tag":"7.4.1","range":[{"fixed":"bcc3cbf4884f0474232a68d3eff060f93a506379"}],"source":"REFERENCES_TAG"}]}}],"versions":["7.4.0","7.3.1","7.3.0","7.2.1","7.2.0","7.1.0","7.0.0","6.0.1","6.0.0","5.1.0","5.0.2","5.0.1","5.0.0","4.2.0","4.1.3","4.1.2","4.1.1","4.1.0","4.0.2","4.0.1","4.0.0","3.2.0","3.2.0-rc.1","3.2.0-rc.2","3.1.0","3.1.0-rc.1","3.0.0","3.0.0-rc.2","3.0.0-rc.1","2.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-126561.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
