How to Fix CVE-2026-32011

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 CVE-2026-32011, 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. 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

## Impact OpenClaw webhook handlers for BlueBubbles and Google Chat accepted and parsed request bodies before authentication and signature checks on vulnerable releases. This allowed unauthenticated clients to hold parser work open with slow/oversized request bodies and degrade availability (slow-request DoS). ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected releases: `<= 2026.3.1` - Latest published vulnerable version at triage time: `2026.3.1` (npm) - Fixed release: `2026.3.2` (released) ## Fix Commit(s) - `d3e8b17aa6432536806b4853edc7939d891d0f25` ## Mitigation Upgrade to `2026.3.2` (or newer). The fix enforces auth-before-body for affected webhook paths, adds strict pre-auth body/time budgets, and introduces shared in-flight/request guardrails with regression coverage.
