What it is

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.

Exploit odds: 0.1% chance of exploitation in the next 30 days (EPSS).
