🚨 Severity: HIGH
πŸ’‘ Vulnerability: Attackers could bypass the command filter using shell quotes to obfuscate blocked tokens.
🎯 Impact: Attackers could execute arbitrary commands and possibly escape the agent's workdir constraints.
πŸ”§ Fix: Validated tokenized arguments against the blocklist instead of the raw command string, effectively catching Unix-style quotation obfuscations.
βœ… Verification: Ran unit tests to verify quotes don't bypass checks.
