CVE-2026-34937

HIGH CVSS 3.1: 7.8 EPSS 0.03%
Updated Apr 07, 2026
Python
Parameter Value
CVSS 7.8 (HIGH)
Fixed In 1.5.90
Type CWE-78 (OS Command Injection)
Vendor Python
Public PoC No

PraisonAI is a multi-agent teams system. Prior to version 1.5.90, run_python() in praisonai constructs a shell command string by interpolating user-controlled code into python3 -c "<code>" and passing it to subprocess.run(..., shell=True). The escaping logic only handles \ and ", leaving $() and backtick substitutions unescaped, allowing arbitrary OS command execution before Python is invoked.

This issue has been patched in version 1.5.90.
