- Summary
- MediaWiki Cross-site Scripting (XSS) vulnerability
- Details
-
An issue was discovered in MediaWiki 1.34.x before 1.34.3. On Special:Contributions, the NS filter uses unescaped messages as keys in the option key for an HTMLForm specifier. This is vulnerable to a mild XSS if one of those messages is changed to include raw HTML.
