New Security Vulnerability Affects Thousands of Self-Managed GitLab Instances

Researchers have disclosed details of a now-patched security vulnerability in GitLab, an open-source DevOps software, that could potentially allow a remote, unauthenticated attacker to recover user-related information.

Tracked as CVE-2021-4191, the medium-severity flaw affects all versions of GitLab Community Edition and Enterprise Edition starting from 13.0 and all versions starting from 14.4 and prior to 14.8.

Following responsible disclosure on November 18, 2021, patches were released as part of GitLab critical security releases 14.8.2, 14.7.4, and 14.6.5 shipped on February 25, 2022.

“The vulnerability is the result of a missing authentication check when executing certain GitLab GraphQL API queries,” Baines said in a report published Thursday.

“The information leak also potentially allows an attacker to create a new username wordlist based on GitLab installations – not just from gitlab.com but also from the other 50,000 GitLab instances that can be reached from the internet,” Baines said.

The patch also addresses six other security flaws, one of which is a critical issue that enables an unauthorized attacker to siphon the runner registration tokens used to authenticate and authorize CI/CD jobs hosted on GitLab instances.
