OpenClaw ACP client has permission auto-approval bypass via untrusted tool metadata
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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`
