How to Fix GHSA-534w-2vm4-89xr

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: 2026.2.24 
npm install openclaw@2026.2.24
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-534w-2vm4-89xr, 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 2026.2.24), 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized 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

A missing group-sender authorization check in the Zalo plugin allowed unauthorized `GROUP` messages to enter agent dispatch paths in configurations intended to restrict group traffic. ## Impact When Zalo group handling was configured with allowlist-style controls, a sender not present in the intended group allowlist could still trigger agent processing through the `GROUP` message path. ## Root Cause Group access checks were not consistently enforced before dispatch for Zalo `GROUP` messages. The fix adds explicit runtime group-policy evaluation (`groupPolicy`, `groupAllowFrom`, fallback to `allowFrom`) and fail-closed behavior for missing provider config. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published vulnerable version: `2026.2.23` (as of 2026-02-24) - Affected range: `<= 2026.2.23` - Planned patched version: `2026.2.24` ## Fix Commit(s) - `b4010a0b627025c809c0e5dbdbd4770f3bc59ef8` OpenClaw thanks @tdjackey for reporting. ### Publication Update (2026-02-25) `openclaw@2026.2.24` is published on npm and contains the fix commit(s) listed above. This advisory now marks `>= 2026.2.24` as patched.
