These issues have been remediated on GitLab.com, and in GitLab CE/EE versions 17.7.7, 17.8.5, and 17.9.2.\n\nOn GitLab CE/EE instances using SAML authentication, under certain circumstances, an attacker with access to a valid signed SAML document from the IdP could authenticate as another valid user within the environment's SAML IdP.\n\nSelf Managed GitLab: Known Mitigations\n\nAffected customers who cannot immediately update GitLab CE/EE to address these issues may choose to perform the following mitigation steps:\n\nNote: This vulnerability requires the attacker to have compromised a valid user account to perform the authentication bypass.\n\n- Enable GitLab two-factor authentication for all user accounts on the GitLab self-managed instance (NOTE: Enabling identity provider multi-factor authentication does not mitigate this vulnerability) and\n\n- Do not allow the SAML two-factor bypass option in GitLab and\n\n- Require admin approval for automatically created new users (gitlab_rails['omniauth_block_auto_created_users'] = true)\n\nhttps://about.gitlab.com/releases/2025/03/12/patch-release-gitlab-17-9-2-released/", "creation_timestamp": "2025-03-13T06:45:02.000000Z"},

An authentication bypass vulnerability was found in ruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential.
