CVE-2025-49578: Starcitizen.tools Citizen

Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

Citizen is a MediaWiki skin that makes extensions part of the cohesive experience. Various date messages returned by `Language::userDate` are inserted into raw HTML, allowing anybody who can edit those messages to insert arbitrary HTML into the DOM. This impacts wikis where a group has the `editinterface` but not the `editsitejs` user right. This vulnerability is fixed in 3.3.1.

Affected products

• Starcitizen.tools Citizen: before 3.3.1 (fixed in 3.3.1)
