Mediawiki · Mediawiki Citizen Skin · CVE-2025-49576
**Name of the Vulnerable Software and Affected Versions**
MediaWiki Citizen Skin versions prior to 3.3.1
**Description**
The issue concerns the Citizen MediaWiki skin, which allows extensions to be part of a cohesive experience. Specifically, the `citizen-search-noresults-title` and `citizen-search-noresults-desc` system messages are inserted into raw HTML. This allows anyone who can edit these messages to insert arbitrary HTML into the DOM, potentially leading to HTML injection.
**Recommendations**
For versions prior to 3.3.1, update to version 3.3.1 to resolve the issue. As a temporary workaround, consider restricting access to editing the `citizen-search-noresults-title` and `citizen-search-noresults-desc` system messages until the update is applied.
