Mattermost · Mattermost · CVE-2025-24866
Name of the Vulnerable Software and Affected Versions:
Mattermost versions 9.11.x through 9.11.8
Description:
The issue is related to improper access controls on the "/api/v4/audits" endpoint, allowing users with delegated granular administration roles who lack access to Compliance Monitoring to retrieve User Activity Logs.
Recommendations:
For Mattermost versions 9.11.x through 9.11.8, consider restricting access to the "/api/v4/audits" endpoint until a patch is available.
As a temporary workaround, review and adjust the delegated granular administration roles to ensure proper access controls are in place.
