CVE-2026-110203 · Severity: high · CVSS 8.8 · Published 2026-10-13

Roo Code, an AI coding assistant, contains a flaw in its automatic command approval system when the "always approve execute" feature is enabled. Attackers can craft shell commands with escaped quotes or special quote syntax that bypass the command allowlist, causing the system to auto-approve dangerous commands like file deletion or system modification that should have been blocked.

## Technical details

The vulnerability lies in the parseCommand function's regex-based quote masking, which uses /"[^"]*"/ to remove quoted strings before command parsing. This regex does not implement bash quoting semantics: it fails to recognize escaped quotes (\"), single quotes, and ANSI-C quotes ($'…') as bash does. An attacker can use commands like echo \";touch /tmp/pwned;\" where bash treats the backslash-escaped quotes as literal characters (allowing the semicolon separator to execute), but the regex incorrectly pairs them and hides the separator in a placeholder, causing the full command to be treated as a single echo sub-command that matches the allowlist. The flaw allows arbitrary command injection when auto-approval is enabled.
