How do I detect CVE-2026-41362 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-2026-41362 if there is no patch (or I can't update yet)?

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.

Is CVE-2026-41362 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-41362 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Summary

Before OpenClaw 2026.3.31, the Zalo webhook replay-dedupe cache was shared across authenticated webhook targets and keyed too broadly. In multi-account deployments, a replay seen on one account could suppress a legitimate event on another account if event_name and message_id matched.

Impact

An attacker who controlled one authenticated Zalo webhook path in a multi-account gateway deployment could cause silent message suppression on a different Zalo account sharing that gateway. This was an availability issue; it did not provide cross-account authentication or data access.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: >= 2026.2.19, < 2026.3.31
Patched versions: >= 2026.3.31

Fix Commit(s)

4d038bb242c11f39e45f6a4bde400e5fd42e4ebf — scope webhook replay dedupe per target

Release Process Note

The initial 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 follow-up hardening for the same surface.
