CVE-2026-44995 · OpenClaw < 2026.4.20 - Arbitrary Code Execution via MCP stdio Environment Variables
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
OpenClaw before 2026.4.20 contains an improper environment variable validation vulnerability in MCP stdio server configuration that allows attackers to execute arbitrary code. Malicious workspace configurations can pass dangerous startup variables like NODE_OPTIONS, LD_PRELOAD, or BASH_ENV to spawned MCP server processes, enabling code injection when operators start sessions using those servers.
