CVE-2026-2287: CrewAI does not properly check that Docker is still running during runtime, and will fall back to a sandbox setting that

CrewAI has a vulnerability where it fails to properly verify that Docker (a containerization tool that isolates applications) is still running during execution. When Docker stops, the software falls back to a less secure sandbox setting that can be exploited for RCE (remote code execution, where an attacker runs commands on a system they don't control).
