How to Fix GHSA-474h-prjg-mmw3

To remediate this vulnerability, upgrade all affected OpenClaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openclaw fixed: 2026.3.2 
npm install openclaw@2026.3.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-474h-prjg-mmw3, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of OpenClaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.3.2), your application is affected.

Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In OpenClaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary Sandboxed `sessions_spawn(runtime="acp")` could bypass sandbox inheritance and initialize host-side ACP runtime. The fix now fail-closes ACP spawn from sandboxed requester sessions and rejects `sandbox="require"` for `runtime="acp"`. ### Affected Packages / Versions - Package: `openclaw` (npm) - Latest published npm version at triage time: `2026.3.1` (March 2, 2026) - Vulnerable range: `<=2026.3.1` - Patched release: `2026.3.2` (released) ### Technical Details - Root cause: `runtime="subagent"` enforced sandbox inheritance, while `runtime="acp"` did not enforce equivalent sandbox/runtime checks. - Security impact: sandbox-boundary bypass into host-side ACP initialization. - Fixed behavior: - deny ACP spawn when requester runtime is sandboxed - deny `sessions_spawn` with `runtime="acp", sandbox="require"` - align sandboxed prompt guidance to avoid advertising blocked ACP paths ### Fix Commit(s) - `ac11f0af731d41743ba02d8595f4d0fe747336e3` - `c703aa0fe92df9fb71cf254fc46991e05fba2114`
