openclawnpmDescription
Vulnerability Summary
The OpenClaw ACP client could auto-approve tool calls based on untrusted metadata and permissive name heuristics. A malicious or compromised ACP tool invocation could bypass expected interactive approval prompts for read-class operations.
Affected Packages / Versions
- Package: npm
openclaw - Affected published versions:
<= 2026.2.22-2(latest published as of February 24, 2026 is2026.2.22-2) - Patched in code on
main:2026.2.23(released)
Technical Details
- Permission classification trusted incoming
toolCall.kindand heuristic name matching. - Non-core read-like names and spoofed kind metadata could reach auto-approve paths.
readoperations were not scoped strongly enough to cwd in all metadata/title forms.
Fix
- Require trusted core tool IDs for auto-approval and ignore untrusted
toolCall.kindas an authorization source. - Scope
readauto-approval to cwd-resolved paths. - Add stricter tool-name validation and regression coverage for spoofed kind and non-core read-like names.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update openclaw to 2026.2.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32898 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-32898 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-32898. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-32898 in your dependencies?
O3 Security finds CVE-2026-32898 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
