Critical CVSS 10 Remote Code Execution Flaw Patched in GitLab
In short: GitLab disclosed a critical vulnerability (CVE-2026-110264, CVSS 10) in its regex compiler that lets an unauthenticated attacker run arbitrary code on affected GitLab servers. The flaw is an integer overflow and affects a broad range of GitLab Community and Enterprise Edition versions. GitLab also patched 2 high, 5 medium and 4 low severity issues in the same release, and published detection rules for exploitation attempts.

- 2Affects GitLab CE/EE versions 7.0 before 18.11.13, and 19.0–19.5 before 19.0.10/19.1.9/19.2.9/19.3.6/19.4.3/19.5.1
- 3Fixed alongside 2 high, 5 medium and 4 low severity vulnerabilities

Why it matters
Any organisation running self-hosted GitLab, especially internet-facing instances, faces a critical risk of full server compromise without authentication, which could expose source code, secrets and CI/CD pipelines.
What it means for AI agents and contact centers
If your company hosts its own GitLab instance (for code, CI/CD, or deployment pipelines related to voice AI or integration projects), check the version immediately and patch to the fixed release, prioritising any internet-facing GitLab servers, then run a compromise assessment using GitLab's published detection rules.
