Which packages are affected by CVE-2026-32898?

CVE-2026-32898 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-32898?

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.

How do I detect CVE-2026-32898 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-2026-32898 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-2026-32898 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-32898 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.

What is the EPSS score for CVE-2026-32898?

CVE-2026-32898 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 18th 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-2026-32898?

CVE-2026-32898 is classified as CWE-807 (CWE-807). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

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 is 2026.2.22-2)
Patched in code on main: 2026.2.23 (released)

Technical Details

Permission classification trusted incoming toolCall.kind and heuristic name matching.
Non-core read-like names and spoofed kind metadata could reach auto-approve paths.
read operations 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.kind as an authorization source.
Scope read auto-approval to cwd-resolved paths.
Add stricter tool-name validation and regression coverage for spoofed kind and non-core read-like names.

Affected Functions

resolvePermissionRequest
resolveToolNameForPermission
shouldAutoApproveToolCall
