GHSA-7jx5-9fjg-hp4m OpenClaw ACP client has permission auto-approval bypass via untrusted tool metadata

• npm openclaw: < 2026.2.23 → fixed in 2026.2.23

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) • `12cc754332f9a7c92e158ce7644aa22df79c0904` • `63dcd28ae0be2de1c75af09cc81841cebeec068f` Found using MCPwner Thanks @nedlir for reporting.
