{"id":"CVE-2026-77609","state":"PUBLISHED","title":"Semantic MediaWiki has an open redirect in Special:URIResolver","description":"Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages. Prior to version 7.2.0, `Special:URIResolver` resolves its user-controlled subpage to a MediaWiki title and issues an HTTP 303 redirect to `$title->getFullURL()` without validating the resolved target. A crafted subpage can make that target point off-host: an interwiki prefix redirects to the foreign wiki (for example `Special:URIResolver/mw-3AFoo`, which decodes to `mw:Foo`, redirects to `https://www.mediawiki.org/wiki/Foo`), and where the resolved URL carries an authority the target can even embed `user:pass@host` credentials. The result is an open redirect to an attacker-influenced host, usable for phishing from a trusted wiki URL. Version 7.2.0 fixes the issue.","publishedAt":"2026-09-18T16:52:16.291Z","updatedAt":"2026-09-22T15:01:26.331Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["SemanticMediaWiki SemanticMediaWiki"],"affected":[{"vendor":"SemanticMediaWiki","product":"SemanticMediaWiki","versions":[{"version":"< 7.2.0","status":"affected"}]}],"references":["https://github.com/SemanticMediaWiki/SemanticMediaWiki/security/advisories/GHSA-hw3m-8j5x-94ff","https://github.com/SemanticMediaWiki/SemanticMediaWiki/releases/tag/7.2.0"],"weaknesses":["CWE-601"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/77xxx/CVE-2026-77609.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-77609","state":"PUBLISHED","datePublished":"2026-09-18T16:52:16.291Z","dateUpdated":"2026-09-22T15:01:26.331Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-08-20T20:48:20.508Z"},"containers":{"cna":{"title":"Semantic MediaWiki has an open redirect in Special:URIResolver","descriptions":[{"lang":"en","value":"Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages.
