Automated description summarized from trusted sources.

CVE-2026-97229 is an integer overflow vulnerability (CWE-190) located in the CI/CD Regular Expression Compiler of GitLab Community Edition (CE) and Enterprise Edition (EE). The flaw stems from insufficient validation of regular expressions used within project pipeline configurations. Under certain conditions, an unauthenticated remote attacker can exploit this vulnerability by supplying a specially crafted regular expression in a CI/CD configuration file (such as `.gitlab-ci.yml`), which can lead to arbitrary code execution on the affected GitLab server. The vulnerability affects self-managed GitLab versions 19.1 through 19.2.7, 19.3 through 19.3.3, and 19.4 through 19.4.1. Security researchers note that exploitation typically requires the ability to commit a configuration file to a repository. However, this constraint is bypassed on instances where self-registration and project creation are enabled for new users. GitLab has addressed the issue in versions 19.4.2, 19.3.4, and 19.2.8, and there have been no confirmed reports of active exploitation in the wild.

Description: GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation.
