CVE-2026-6552 Details
Description
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.
A vulnerability has been addressed in GitLab EE versions 15.5 prior to 18.10.8, 18.11 prior to 18.11.5, and 19.0 prior to 19.0.2. Under certain conditions, this vulnerability could have allowed an authenticated user with the group Owner role to take over another group member's GitLab account. This issue arose from improper authorization in the Group SAML identity management functionality.
