CVE-2026-19228 is a high-severity authorization bypass vulnerability in GitLab Enterprise Edition affecting versions 19.1 before 19.1.4 and 19.2 before 19.2.2. The flaw is caused by improper authorization of identity information supplied in requests, allowing a user-controlled identity value to be trusted when processing AI-related operations in the Duo Workflow Service. Under certain conditions, an authenticated user can cause AI usage to be attributed to a different namespace than the one they are authorized to act for. The issue is remotely exploitable and affects the integrity of namespace-scoped accounting and authorization decisions around AI usage attribution.
