Description OSIDB Bzimport 2026-09-23 23:21:33 UTC 
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 that under certain conditions could have allowed an authenticated user to execute arbitrary code on the GitLab server due to an integer overflow issue when compiling a specially crafted regular expression in a CI/CD configuration.
