CVE-2025-53902Public exploitNetwork attack vector

Restricted artifact disclosure via unchecked notification recipients

Published Jul 29, 2025 · Updated Jul 29, 2025

Incorrect authorization in Enalean Tuleap allows remote authenticated users to read restricted tracker artifacts through notification emails. The notification recipient path includes mentioned users and sends artifact content without checking each recipient's artifact-read permission. A valid low-privilege account and a mention in a tracker update are required; the resulting exposure is limited to confidential artifact data.
