Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
openclawnpmDescription
OpenClaw versions 2026.2.19 before 2026.3.31 contain an improper cache isolation vulnerability in the Zalo webhook replay-dedupe mechanism that is shared across authenticated webhook targets. Attackers controlling one authenticated Zalo webhook path in multi-account deployments can suppress legitimate events on different accounts by matching event_name and message_id parameters.
Affected Packages

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 2026.3.31 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-41362 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 CVE-2026-41362 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 CVE-2026-41362. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
