CVE-2026-103515PATCHED
GitLab · GitLab EE

Incorrect Authorization in GitLab

Description

GitLab has remediated multiple vulnerabilities affecting GitLab Community Edition (CE) and Enterprise Edition (EE). These vulnerabilities allow remote arbitrary code execution, data confidentiality breach, and security policy bypass. Affected versions include 19.2.x before 19.3.6, 19.4.x before 19.4.3, and 19.5.x before 19.5.1. One specific issue involves insufficient granularity of admin-lock enforcement controls for group Duo availability, allowing authenticated group Owners to re-enable AI-backed data egress to third-party services.
