A high-severity vulnerability in GitLab Community Edition and Enterprise Edition allows an attacker, under certain circumstances, to trigger a CI/CD pipeline as another user. The issue affects all versions starting from 11.6 before 17.2.9, starting from 17.3 before 17.3.5, and starting from 17.4 before 17.4.2. Available reporting ties the flaw to GitLab import functionality and indicates that exploitation can cause pipeline execution to occur with another user’s identity rather than the attacker’s own context, resulting in unauthorized actions within the CI/CD workflow.
