CVE-2026-27883Public exploitNetwork attack vector

Cross-team disclosure via unscoped deployment lookup

Published Jun 30, 2026 · Updated Jun 30, 2026

Authorization bypass in Coolify before 4.0.0-beta.464 allows remote authenticated users to read other teams' deployment details. DeployController.php's deployment_by_uuid method extracts the token's team identifier but queries ApplicationDeploymentQueue only by the supplied deployment UUID. A valid API token and a victim deployment UUID are required; exposed records include application, server, commit, URL, and possibly sensitive build-log data.
