mediawiki/semantic-media-wiki is vulnerable to Cross-Site Scripting (XSS)
48
Medium Risk
This Affects:
mediawiki/semantic-media-wikiTL;DR
The schema page writes a schema description, tag, type link, and JSON body into the page without escaping. A user with smw-schemaedit can store markup in those fields, and another user who views the schema page receives it as HTML, leading to stored cross-site scripting. The fix escapes those fields before rendering.
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 schemas.
