CVE ID :CVE-2026-34955
Published : April 4, 2026, 12:16 a.m. | 51 minutes ago
Description :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 ''. This issue has been patched in version 4.5.97.
Severity: 8.8 | HIGH
