Summary

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Coolify versions prior to and including v4.0.0-beta.420.8 have an information disclosure vulnerability in the `/api/v1/teams/{team_id}/members` and `/api/v1/teams/current/members` API endpoints allows authenticated team members to access a highly sensitive `email_change_code` from other users on the same team. This code is intended for a single-use email change verification and should be kept secret. Its exposure could enable a malicious actor to perform an unauthorized email address change on behalf of the victim. As of time of publication, no known patched versions exist.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
