What is CVE-2026-29782?

OpenSTAManager, an open source management software for technical assistance and invoicing, contains a vulnerability in the oauth2.php file prior to version 2.10.2. This file acts as an unauthenticated endpoint, allowing attackers to manipulate the GET parameter 'state' to load records from the zz_oauth2 table. Furthermore, during the OAuth2 configuration process, the software calls unserialize() on the access_token field without class restrictions, which may lead to the execution of arbitrary code. Users are encouraged to update to version 2.10.2 or later to mitigate this issue.

Affected Version(s)

openstamanager < 2.10.2
