Description
Roo-Code through 3.54.0 contains an auto-approve bypass vulnerability in the shell command parsing logic that allows attackers to execute denied shell commands by exploiting the omission of the bash pipe operator from the command parser's operator token set. Attackers can craft a command line with an allowlisted prefix followed by the stderr-redirecting pipe operator and a denied command, causing the parser to approve the full pipeline while bash executes the denied component with the agent's auto-execute privileges on the developer's machine.
