CERT-FR has published an advisory regarding a security policy bypass vulnerability affecting GitLab Community Edition (CE), Enterprise Edition (EE), and AI Gateway. The flaw, tracked as CVE-2026-111943, allows an attacker to circumvent security policy enforcement mechanisms within affected GitLab deployments.
Multiple version branches are affected across both GitLab CE/EE and the AI Gateway component, spanning versions 18.11.x through 19.5.x. GitLab has released patched versions for each affected branch (e.g., 19.5.3, 19.4.5, 19.3.7, etc., and corresponding AI Gateway fixes). The advisory does not indicate evidence of active exploitation in the wild; it is a standard vendor disclosure accompanied by a CERT-FR relay notice.
Defenders running self-hosted GitLab instances or AI Gateway deployments should identify their current version against the affected ranges listed and apply the vendor's patches promptly, referencing GitLab's October 29, 2026 security release notes. No indicators of compromise or exploitation details were provided in this bulletin.
