CVE-2026-77606
Semantic MediaWiki is a free, open-source extension to MediaWiki that lets users store and query data within the wiki's pages.
Impact
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, when `headers=plain`, table header text was emitted into `<th>` via a raw HTML path. User-controlled `mainlabel` content could therefore become executable HTML. Version 7.2.0 fixes the issue.
