Name of the Vulnerable Software and Affected Versions:
Mediawiki - Wikidata Extension versions 1.39 through 1.43
Description:
The issue is related to improper input validation in the Mediawiki - Wikidata Extension, allowing Cross-Site Scripting (XSS) from the
widthheight message via the ImageHandler::getDimensionsString() function.Recommendations:
For versions 1.39 through 1.43, consider disabling the
ImageHandler::getDimensionsString() function as a temporary workaround until a patch is available. Restrict access to the widthheight message in the affected API endpoint to minimize the risk of exploitation.Exploit
