What is CVE-2026-32898?

The OpenClaw ACP client prior to version 2026.2.23 is susceptible to an authorization bypass vulnerability. This issue allows attackers to bypass interactive approval prompts for read-class operations by utilizing untrusted toolCall.kind metadata. By exploiting permissive name heuristics, an attacker can manipulate tool metadata or use non-core names effectively, leading to unauthorized auto-approvals of tool actions.
