How to Fix CVE-2026-41301

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: 2026.3.31
npm install openclaw@2026.3.31
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-2026-41301, 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 2026.3.31), 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-347: Improper Verification of Cryptographic Signature, where the product does not verify, or incorrectly verifies, the cryptographic signature for 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

## Summary Before OpenClaw 2026.3.31, the Nostr DM ingress path could issue pairing challenges before validating the event signature. A forged DM could create a pending pairing entry and trigger a pairing-reply attempt before signature rejection. ## Impact An unauthenticated remote sender could consume shared pairing capacity and trigger bounded relay/logging work on the Nostr channel. This issue did not grant message decryption, pairing approval, or broader authorization bypass. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `>= 2026.3.22, < 2026.3.31` - Patched versions: `>= 2026.3.31` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `4ee742174f36b5445703e3b1ef2fbd6ae6700fa4` — verify inbound DM signatures before pairing replies ## Release Process Note The fix shipped in OpenClaw `2026.3.31` on March 31, 2026. The current published npm release `2026.4.1` from April 1, 2026 also contains the fix. Thanks @smaeljaish771 for reporting.
