Vulnerability Summary

CVE-2026-29782: OpenSTAManager is an open source management software for technical assistance and invoicing. Prior to version 2.10.2, the oauth2.php file in OpenSTAManager is an unauthenticated endpoint ($skip_permissions = true).

This issue has been patched in version 2.10.2.
