CVE-2026-34955

HIGH CVSS 3.1: 8.8 EPSS 0.01%
Updated Apr 07, 2026
Praisonai
Parameter Value
CVSS 8.8 (HIGH)
Fixed In 4.5.97
Type CWE-78 (OS Command Injection)
Vendor Praisonai
Public PoC No

PraisonAI is a multi-agent teams system. Prior to version 4.5.97, SubprocessSandbox in all modes (BASIC, STRICT, NETWORK_ISOLATED) calls subprocess.run() with shell=True and relies solely on string-pattern matching to block dangerous commands. The blocklist does not include sh or bash as standalone executables, allowing trivial sandbox escape in STRICT mode via sh -c '<command>'.

This issue has been patched in version 4.5.97.
