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

Affected: OpenClaw

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.

GHSA-3qpv-xf3v-mm45 — OpenClaw: Workspace `.env` can override the bundled hooks root and load attacker hook code

Affected: npm: openclaw

## Summary Workspace `.env` can override the bundled hooks root and load attacker hook code

## Current Maintainer Triage - Status: open - Normalized severity: high - Assessment: v2026.3.28 still lets workspace .env override OPENCLAW_BUNDLED_HOOKS_DIR, which can replace trusted default-on bundled hooks from an untrusted workspace.

## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version: `2026.3.31` - Vulnerable version range: `<=2026.3.28` - Patched versions: `>= 2026.3.31` - First stable tag containing the fix: `v2026.3.31`
