CVE-2026-41336: OpenClaw < 2026.3.31 - Arbitrary Hook Code Execution via OPENCLAW_BUNDLED_HOOKS_DIR Environment Variable Override

OpenClaw before 2026.3.31 allows workspace .env files to override the OPENCLAW_BUNDLED_HOOKS_DIR environment variable, enabling loading of attacker-controlled hook code. Attackers can replace trusted default-on bundled hooks from untrusted workspaces to execute arbitrary code.
