CVE-2026-57117: PraisonAI shell command injection in compute-bridged file tools

CVE-2026-57117 · Severity: high · CVSS 8.8 · Published 2026-10-23

PraisonAI is a multi-agent system that delegates file operations to compute environments. When a compute provider is attached, the file tools (read, list, write) are converted to shell commands with unsanitized path arguments, allowing attackers to inject shell metacharacters and execute arbitrary commands on the host or in containers. This bypasses tool restrictions and can lead to unauthorized command execution in the deployment environment.

Technologies: MervinPraison PraisonAI, praisonai (PyPI). Vendors: MervinPraison, PyPI.

How to fix

  • praisonai (PyPI): upgrade to 4.6.59 or later
    pip install "praisonai>=4.6.59"

Technical details

The LocalManagedAgent and SandboxedAgent compute bridging layer wraps file operations (read_file, list_files, write_file) by constructing shell command strings with raw path arguments, then executing them via subprocess or Docker. An attacker who can influence a path argument can break out of the quoted path using shell metacharacters (e.g., `"; command; #`) to execute arbitrary shell commands. The vulnerability affects versions 4.6.10 through 4.6.57, and is fixed in 4.6.59.
