description

GitLab CE/EE releases before the listed fixed versions are affected by an integer overflow during compilation of certain regular expressions. Under certain conditions, an unauthenticated attacker could execute code on the GitLab server by causing processing of a crafted regular expression.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Upgrade GitLab to 18.11.13, 19.0.10, 19.1.9, 19.2.9, 19.3.6, 19.4.3, 19.5.1, or a later applicable release. Restrict unauthenticated access to GitLab until the upgrade is complete.

fixed in 18.11.13, 19.0.10, 19.1.9, 19.2.9, 19.3.6, 19.4.3, 19.5.1
