How to Fix CVE-2026-27484

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: 2026.2.18 
npm install openclaw@2026.2.18
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 CVE-2026-27484, 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 2026.2.18), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. 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

## Overview Discord moderation action handling (`timeout`, `kick`, `ban`) used sender identity from request parameters in tool-driven flows, instead of trusted runtime sender context. ## Impact In setups where Discord moderation actions are enabled and the bot has the necessary guild permissions, a non-admin user could request moderation actions by spoofing sender identity fields. ## Affected Packages / Versions - Package: `openclaw` (npm) - Latest published affected version (as of 2026-02-19): `2026.2.17` - Affected range: `<=2026.2.17` - Fixed in planned next release: `2026.2.18` ## Fix - Moderation authorization now uses trusted sender context (`requesterSenderId`) instead of untrusted action params. - Added permission checks for required guild capabilities per action. ## Fix Commit(s) - `775816035ecc6bb243843f8000c9a58ff609e32d` Thanks @aether-ai-agent for reporting.
