mediawiki/semantic-media-wiki is vulnerable to Cross-Site Scripting (XSS)
48
Medium Risk
This Affects:
mediawiki/semantic-media-wikiTL;DR
Special:Browse uses a property group schema's canonical_name as the section heading without escaping. The schema pattern accepts any string, and a user with smw-schemaedit can store markup in that name. Anyone who browses a page in that group receives the heading as HTML, leading to stored cross-site scripting. The fix escapes the heading before output.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and a user with smw-schemaedit can edit property group schemas.
