Summary

An authorization bypass vulnerability has been identified in GitLab, allowing attackers to circumvent the CODEOWNERS functionality. This weakness is present in multiple versions of the product, specifically those from 11.3 leading up to earlier versions, culminating in versions 16.9.2. By utilizing a specially crafted payload embedded in an old feature branch, an unauthorized actor may perform malicious actions typically restricted by permissions. The risk this presents underscores the importance of maintaining updated versions and understanding the implications of version compatibility.

Affected Version(s)

GitLab 11.3 < 16.7.7

GitLab 16.8 < 16.8.4

GitLab 16.9 < 16.9.2

Exploit Proof of Concept (PoC)
