Name of the Vulnerable Software and Affected Versions
MediaWiki RSS extension versions prior to 2022-04-29
Description
The issue allows XSS via an rss element if the feed is in $wgRSSUrlWhitelist and $wgRSSAllowLinkTag is true.
Recommendations
For versions prior to 2022-04-29, update to a version released after 2022-04-29 to resolve the issue. As a temporary workaround, consider setting $wgRSSAllowLinkTag to false to minimize the risk of exploitation. Restrict access to feeds not in $wgRSSUrlWhitelist to further reduce the risk.
