description

IntentKit through 2.6.3 may authorize tool requests against a broader registry than the tools permitted for an individual request. Public or unauthenticated callers using exposed web, API, or messaging integrations could trigger owner-restricted state-changing actions without the intended approval step.

mitigation

Restrict or disable public access to affected web, API, and messaging integrations, and disable owner-capable state-changing tools until authorization is verified. Require authenticated, isolated request handling and do not reuse untrusted thread, checkpoint, or history data.
