CVE-2026-37008

Sandbox Escape via ctypes.CDLL in CrewAI

Published Sep 13, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
CrewAI before fb2323b offers a Python blocklist approach that operates at the wrong level of abstraction, a different vulnerability than CVE-2026-2275. Import-time blocking of module names does not address the availability of Python's complete object graph. For example, calling ctypes.CDLL(None) loads the C library without relying in any import statements. In other words, a within-process sandbox cannot merely account for the import system and instead must account for the complete runtime of the Python interpreter.
