CVE-2026-97229 · Severity: critical · CVSS 10 · Exploited in the wild · Published 2026-10-13

GitLab is a code hosting and CI/CD platform used by development teams. An integer overflow vulnerability in GitLab's CI/CD pipeline configuration processor allows an unauthenticated attacker to execute arbitrary code on the server by uploading a malicious regular expression pattern. This could lead to complete compromise of the GitLab instance, exposing all source code, secrets, and data stored within.

## How to fix

- Fixed in GitLab CE/EE 19.2.8, 19.3.5, 19.4.2

## Technical details

An integer overflow in the CI/CD regular expression compiler allows unauthenticated remote code execution via a specially crafted regex in a CI/CD configuration file. The vulnerability stems from insufficient validation of regular expressions before compilation. Exploitation requires no authentication, no user interaction, and results in arbitrary code execution with full server privileges.
