> Multiple flaws in GitLab allow privilege escalation, DoS, confidentiality breach, and code injection across versions 19.0, 19.1, and 19.2.

CERT-FR published an advisory on multiple vulnerabilities affecting GitLab Community Edition (CE) and Enterprise Edition (EE). The affected versions include all releases prior to 19.0.6, versions 19.1.x prior to 19.1.4, and versions 19.2.x prior to 19.2.2. The vulnerabilities expose organizations to privilege escalation, remote denial of service, data confidentiality breaches, security policy bypass, and cross-site scripting (XSS) attacks. The CERT-FR advisory references twelve distinct CVEs published by GitLab on 12 August 2026. Defenders should prioritize patching affected GitLab instances to the fixed versions immediately, as the attack surface spans multiple critical impact categories that could compromise repository integrity and user data.
