Description

Summary

Gateway auth for plugin channel endpoints can be bypassed when path canonicalization differs between the gateway guard and plugin handler routing.

Details

On affected versions, server-http only applies gateway auth when raw requestPath matches exactly:

  • /api/channels
  • /api/channels/*

If a plugin handler canonicalizes path input (for example decodeURIComponent(pathname).toLowerCase()), requests like:

  • /API/channels/nostr/default/profile
  • /api/channels%2Fnostr%2Fdefault%2Fprofile can be interpreted as /api/channels/* by the plugin, while the gateway auth guard is skipped.

Impact

Authentication boundary bypass for plugin channel HTTP routes under canonicalization mismatch conditions. Unauthorized callers may access plugin channel APIs that are expected to require gateway auth.

CWE: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) CVSS: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N (Base 5.3, Moderate)

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.2.26 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8j2w-6fmm-m587 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
