CVE-2026-57136Public exploitNetwork attack vectorHinoki check available

Arbitrary command execution via first-token allowlist bypass

Published Sep 15, 2026 · Updated Sep 15, 2026

OS command injection in SandboxExecutor 1.2.3 through 1.7.1 allows remote authenticated users to run arbitrary shell commands. CommandValidator checks only the first whitespace-delimited token against allowedCommands before the complete unmodified string is interpreted by sh -c. Exploitation requires a consuming application, CLI workflow, or agent pipeline to pass lower-trust input into sandbox execution, granting the command the PraisonAI process privileges.
