Roo Code through 3.54.0 contains a command approval bypass vulnerability in parseCommandLine() that allows attackers to auto-approve arbitrary shell commands by placing a command substitution in command position. Attackers using indirect prompt injection can submit commands like $(echo touch /tmp/x) that pass the echo allowlist check, causing the shell to execute the output without user approval.
