Attackers Target Maximum-Severity GitLab Flaw Following Patch Release

Attackers recently attempted to exploit a maximum-severity flaw in GitLab just days after a security fix was published. The vulnerability allows malicious actors to execute arbitrary code on the server through manipulated configuration settings. Businesses hosting their own development environments face immediate risk if these critical updates are delayed.
