Base vector

AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N

Name of the Vulnerable Software and Affected Versions: MediaWiki versions through 1.36

Description: An issue was discovered in the Translate extension where the Aggregategroups Action API module does not validate the parameter for aggregategroup when action=remove is set. This allows users with the translate-manage right to silently delete various groups' metadata.

Recommendations: For MediaWiki versions through 1.36, as a temporary workaround, consider restricting access to the Aggregategroups Action API module until a patch is available. Avoid using the aggregategroup parameter in the affected API endpoint when action=remove is set until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
