How the CVE Works
CVE-2025-3396 exploits a flaw in GitLab EE’s API request handling, allowing authenticated project owners to bypass group-level forking restrictions. Attackers manipulate API calls to circumvent configured policies, enabling unauthorized repository forks. The vulnerability stems from improper validation of user permissions during API interactions, specifically in fork request processing. By crafting malicious API requests, attackers can bypass group-level controls, violating intended access restrictions.
