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.

CrewAI before 1.15.1 contains a server-side request forgery vulnerability in the validate_url function that performs one-shot DNS resolution and blocklist checks before returning the original URL unchanged. Attackers can bypass the security filter by supplying URLs that redirect to internal addresses or use DNS rebinding techniques to access internal services and cloud metadata endpoints.

CrewAI does not properly check that Docker is still running during runtime, and will fall back to a sandbox setting that allows for RCE exploitation.

CrewAI contains a server-side request forgery vulnerability that enables content acquisition from internal and cloud services, facilitated by the RAG search tools not properly validating URLs provided at runtime.

CrewAI contains a arbitrary local file read vulnerability in the JSON loader tool that reads files without path validation, enabling access to files on the server.

The CrewAI CodeInterpreter tool falls back to SandboxPython when it cannot reach Docker, which can enable RCE through arbitrary C function calling.
