IBM Langflow OSS Remote Code Execution via Deserialization

IBM Langflow OSS versions 1.0.0 through 1.10.0 contain a critical deserialization vulnerability (CVE-2026-8476) in its disk-based caching mechanism, which uses Python's unsafe `pickle.loads()` function without proper validation, allowing attackers to process malicious pickle payloads and achieve arbitrary code execution with the privileges of the Langflow server process, leading to complete system compromise.
