OpenSTAManager: Remote Code Execution via Insecure Deserialization in OAuth2

Published Apr 2, 2026 · Updated Apr 3, 2026 · Assigned by GitHub_M

Vendor: devcode-it Product: openstamanager Package: devcode-it/openstamanager Ecosystem: Packagist

Description

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). It loads a record from the zz_oauth2 table using the attacker-controlled GET parameter state, and during the OAuth2 configuration flow calls unserialize() on the access_token field without any class restriction. This issue has been patched in version 2.10.2.
