How do I detect CVE-2026-35660 in my npm dependencies?

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.

How do I mitigate CVE-2026-35660 if there is no patch (or I can't update yet)?

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.

Is CVE-2026-35660 actively exploited in the wild?

What is the EPSS score for CVE-2026-35660?

CVE-2026-35660 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 20th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-35660?

CVE-2026-35660 is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

Summary

Before v2026.3.23, the Gateway agent RPC accepted /reset and /new for callers with only operator.write, even though the direct sessions.reset RPC correctly requires operator.admin.

Affected Packages / Versions

Package: openclaw (npm)
Affected: < 2026.3.23
Fixed: >= 2026.3.23
Latest released tag checked: v2026.3.23-2 (630f1479c44f78484dfa21bb407cbe6f171dac87)
Latest published npm version checked: 2026.3.23-2

Root Cause

The vulnerable path lived in src/gateway/server-methods/agent.ts. A /reset or /new message with an explicit sessionKey reached performGatewaySessionReset(...) without enforcing the same operator.admin guard used by sessions.reset.

Fix Commit(s)

50f6a2f136fed85b58548a38f7a3dbb98d2cd1a0 — fix(gateway): require admin for agent session reset

Release Status

The fix commit is contained in released tags v2026.3.23 and v2026.3.23-2. The latest shipped tag and npm release both include the fix.

Code-Level Confirmation

src/gateway/server-methods/agent.ts now rejects /reset and /new for callers that do not have operator.admin before calling performGatewaySessionReset(...).
src/gateway/server-methods/agent.test.ts contains the regression test rejects /reset for write-scoped gateway callers.
