GHSA-8j2w-6fmm-m587
MEDIUMGHSA-8j2w-6fmm-m587 is a medium-severity (CVSS 4.8) CWE-288 vulnerability in openclaw. O3 Security confirms whether GHSA-8j2w-6fmm-m587 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw: /api/channels gateway-auth boundary bypass via path canonicalization mismatch
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
openclawnpmDescription
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%2Fprofilecan 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 dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-8j2w-6fmm-m587 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-8j2w-6fmm-m587. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-8j2w-6fmm-m587 in your dependencies?
O3 detects GHSA-8j2w-6fmm-m587 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
