How to Fix CVE-2026-44999

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: 2026.4.20 
npm install openclaw@2026.4.20
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-2026-44999, 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 2026.4.20), 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-345: Insufficient Verification of Data Authenticity, where the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. 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

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `< 2026.4.20` - Patched version: `2026.4.20` ## Impact Output from webhook-triggered isolated cron agent runs could be queued into the main session awareness stream without `trusted: false`. That made the event render as a trusted `System:` event instead of an untrusted system event. This is a trust-labeling issue that can strengthen prompt-injection impact, but it does not directly bypass gateway auth, tool policy, or sandboxing. Severity is low. ## Fix OpenClaw now preserves untrusted labels for isolated cron awareness events and forwards the trust flag through cron delivery helpers. Fix commit: - `f61896b03cc7031f51106a04566831f4ac2a0bd7` ## Release Fixed in OpenClaw `2026.4.20`.
