The flaw affects an engine that processes regular expressions in configuration files and can be exploited by unauthenticated users under certain conditions.
The company has issued patches across multiple versions of both Community and Enterprise editions and strongly recommends immediate updates. Security tracking shows over 2,700 GitLab Community Edition instances are currently exposed online. This represents the latest in a series of severe vulnerabilities affecting GitLab’s platform, which serves over 30 million users worldwide and is utilized by more than half of Fortune 100 companies.
