Affected: Homebrew: openclaw-cli

## 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`

## Fix Commit(s)

 https://vulnerability.circl.lu/vuln/cve-2026-32898 CVE-2026-32898 — OpenClaw < 2026.2.23 - ACP Permission Auto-Approval Bypass via Untrusted Tool Metadata 2026-10-02T15:08:08.619380+00:00

Affected: OpenClaw

OpenClaw versions prior to 2026.2.23 contain an authorization bypass vulnerability in the ACP client that auto-approves tool calls based on untrusted toolCall.kind metadata and permissive name heuristics. Attackers can bypass interactive approval prompts for read-class operations by spoofing tool metadata or using non-core read-like names to reach auto-approve paths.
