CVE-2026-93577: GitLab integer overflow in regular expression compiler

CVE-2026-93577 · Severity: critical · CVSS 9.9 · Published 2026-09-24

GitLab CE and EE contain an integer overflow vulnerability in the regular expression compiler used to process CI/CD pipeline configurations. An authenticated attacker can exploit this flaw by crafting a malicious regular expression to execute arbitrary code on the GitLab server with full system privileges. This vulnerability affects widely-used versions of GitLab and requires immediate patching to prevent compromise of source code, CI/CD pipelines, and the underlying infrastructure.

Technologies: GitLab EE, GitLab CE. Vendors: GitLab.

Technical details

An integer overflow in the regular expression compiler component allows authenticated users to trigger arbitrary code execution when parsing specially crafted regex patterns in CI/CD configurations. The vulnerability requires authentication and network access, but no user interaction. Exploitation grants complete remote code execution as the GitLab service account. Patches are available in versions 19.2.7, 19.3.3, and 19.4.1.
