Red Hat Web Terminal
Monthly
Container privilege escalation in Red Hat Web Terminal allows local attackers with group membership to modify the /etc/passwd file and create arbitrary user accounts including root. The vulnerability stems from overly permissive group-writable permissions on /etc/passwd during image build, enabling privilege escalation from non-root container users to full root access within the container. Red Hat Web Terminal across multiple versions is affected; no public exploit code or active exploitation has been reported at the time of analysis.
