CVE-2026-28393
OpenClaw's hook transform module path allows traversal and arbitrary JavaScript module loading
Description
## Summary OpenClaw hook mapping transforms could be loaded via absolute paths or `..` traversal, allowing arbitrary JavaScript module loading/execution in the gateway process when an attacker can modify hooks configuration. ## Affected Versions - Affected: >= 2.0.0-beta3 and <= 2026.2.13 - Fixed: 2026.2.14 ## Details `hooks.mappings[].transform.module` is dynamically imported and executed during webhook processing. Path resolution previously accepted absolute paths and did not enforce containment for relative paths, so a config-controlled transform could resolve outside the intended transforms directory. ## Impact If an attacker can write the OpenClaw config (or otherwise update hooks config through authenticated configuration mechanisms), they could point a hook mapping transform at an arbitrary module on disk and execute code with the gateway process privileges. ## Reproduction (config-controlled module load) 1. Configure a hook mapping that points to a transform path that escapes the transforms directory (for example via `..` traversal). 2. Place a malicious ESM module at the resolved location that executes arbitrary code in the gateway process. 3. Trigger the hook endpoint with the correct hook token. ## Fix Transform loading is now constrained to the OpenClaw transforms root directory: - Root: `~/.openclaw/hooks/transforms` - `hooks.transformsDir` must be within that directory - `transform.module` must be within the selected transforms directory Attempts to escape the root (absolute paths outside, `..` traversal) are rejected.
