No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Roo-Code through 3.54.0 contains an auto-approve bypass vulnerability that allows attackers to execute denied shell commands by exploiting a word-boundary mismatch in comment handling between the approval gate's shell parser and bash. Attackers can craft a command string with an allowlisted word immediately followed by a hash character, separator, and denied command to pass the approval gate while bash executes the denied command with the agent's auto-execute privileges on the developer's machine.
