QID 998064

QID 998064: PHP (Composer) Security Update for mediawiki/core (GHSA-pfm2-mqwj-ggm5)

In MediaWiki before 1.34.1, users can add various Cascading Style Sheets (CSS) classes (which can affect what content is shown or hidden in the user interface) to arbitrary DOM nodes via HTML content within a MediaWiki page. This occurs because jquery.makeCollapsible allows applying an event handler to any Cascading Style Sheets (CSS) selector. There is no known way to exploit this for cross-site scripting (XSS).

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.

CVSS V3 rated as Medium - 5.3 severity.

CVSS V2 rated as Medium - 5 severity.
