CVE-2025-9486Network attack vectorHinoki check available

Privilege gain via ignored pending-membership state

Published Aug 12, 2026 · Updated Aug 12, 2026

Incorrect privilege assignment in affected GitLab EE releases allows remote authenticated users to gain custom-role permissions. The custom-role authorization path grants assigned permissions without excluding users whose group membership remains pending. Exploitation requires high-privileged access and specific membership conditions; resulting access is limited to the assigned custom role.
