CVE-2026-6552 · UBUNTU-CVE-2026-6552
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Rejected reason: This CVE ID has been rejected. GitLab determined that the reported behavior does not constitute a vulnerability: linking a group SAML identity requires the user to explicitly consent to that group controlling their GitLab account for sign-in, and management of group SAML identities by a group Owner is therefore expected behavior rather than an authorization bypass. No GitLab version was affected.
