CVE-2026-82537Public exploitNetwork attack vector

Command execution via shell comment parsing mismatch

Published Sep 8, 2026 · Updated Sep 8, 2026

Command injection in Roo Code 3.54.0 and earlier allows attackers to execute denied shell commands through the auto-approve feature. The parseCommand token loop discards shell-quote comment objects after a word-attached hash, while bash treats the hash as literal and executes the hidden separator and command. Exploitation requires always-approve execution and attacker-influenced agent input; commands run with the agent's local privileges.
