{"id":"UBUNTU-CVE-2026-6552","details":"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.","modified":"2026-08-06T03:11:24.203747904Z","published":"2026-06-11T12:16:00Z","upstream":["CVE-2026-6552"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-6552"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-6552"},{"type":"REPORT","url":"https://about.gitlab.com/releases/2026/06/10/patch-release-gitlab-19-0-2-released/"},{"type":"REPORT","url":"https://gitlab.com/gitlab-org/gitlab/-/work_items/597295"},{"type":"REPORT","url":"https://hackerone.com/reports/3655189"}],"affected":[{"package":{"name":"gitlab","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/gitlab?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["8.4.3+dfsg-9","8.4.3+dfsg-12","8.5.8+dfsg-5"],"ecosystem_specific":{"binaries":[{"binary_version":"8.5.8+dfsg-5","binary_name":"gitlab"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-6552.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
