CVE-2026-57136 Details
Description
PraisonAI is a multi-agent teams system. From 1.2.3 until 1.7.2, CommandValidator in src/praisonai-ts/src/cli/features/sandbox-executor.ts validates only the first whitespace-delimited executable against allowedCommands, then SandboxExecutor passes the complete command string to sh -c. A command beginning with an allowed executable can append a non-allowlisted command through shell metacharacters, causing arbitrary commands to run with the PraisonAI process privileges. This issue is fixed in version 1.7.2.
A vulnerability in PraisonAI versions 1.2.3 prior to 1.7.2 allows for arbitrary command execution through a command validation bypass. The issue arises in the 'CommandValidator' component, which only checks the first executable in a command string against an allowlist. The 'SandboxExecutor' then passes the entire command to the shell, creating an opportunity for exploitation. By appending non-allowlisted commands using shell metacharacters, unauthorized commands can be executed with the privileges of the PraisonAI process.
Users can update to PraisonAI version 1.7.2 or later, where this vulnerability has been fixed.
