CVE-2026-32898
OpenClaw < 2026.2.23 - ACP Permission Auto-Approval Bypass via Untrusted Tool Metadata
Description
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.
