DescriptionCVE.org

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

AnalysisAI

Remote code execution in CrewAI's CodeInterpreter tool occurs when Docker connectivity fails and the system falls back to SandboxPython, allowing unauthenticated remote attackers to execute arbitrary C functions and achieve code execution. The vulnerability affects systems relying on CrewAI's code execution capabilities where Docker is unavailable or unreachable, creating a dangerous fallback condition that bypasses intended sandboxing protections.

Technical ContextAI

CrewAI's CodeInterpreter tool is designed to safely execute code by preferentially using Docker containerization for isolation. However, when Docker is inaccessible (network unavailable, service down, or misconfigured), the tool falls back to SandboxPython, a lighter-weight execution environment. SandboxPython does not adequately restrict the ability to call arbitrary C functions, which are typically available through Python's ctypes or similar FFI mechanisms. This fallback behavior means that threat models assuming Docker-based isolation are violated when Docker becomes unavailable, leaving execution sandboxing dependent on weaker SandboxPython protections. The vulnerability chain is: Docker unreachable → fallback to SandboxPython → C function calling permitted → arbitrary code execution.

RemediationAI

Primary remediation requires ensuring Docker is reliably available and reachable when CrewAI's CodeInterpreter tool is deployed; configure the tool to fail securely (raise an error, do not execute) rather than fall back to SandboxPython when Docker is unavailable. Monitor Docker daemon health and network connectivity to prevent unintended fallback scenarios. Users should immediately check for security updates from CrewAI addressing this vulnerability and review deployment architecture to eliminate reliance on the SandboxPython fallback for code execution safety. Consult the CERT/CC advisory at https://www.kb.cert.org/vuls/id/221883 and CrewAI's official documentation for patch availability and detailed remediation guidance. Until patched, restrict CodeInterpreter tool access to trusted code sources and monitor execution logs for signs of C function abuse.
