Summary

IntentKit through 2.6.3, fixed in commit 5b91da5, contains an authorization bypass where the executor validates tool calls against the full tool registry rather than the per-request narrowed tool advertisement enforced by ToolBindingMiddleware. This allows owner-only state-changing tools such as wallet transfer, posting, memory-write, and call-agent to execute without any human-in-the-loop or approval gate.

Risk Assessment

An unauthenticated or public caller can execute owner-restricted operations such as fund transfers or content posting, leading to unauthorized actions and potential losses.

Recommendation

Upgrade IntentKit to a version containing commit 5b91da5 and restrict access to WEB, API, TWITTER, and TELEGRAM contexts to trusted users.

Original NVD description (English source)

IntentKit through 2.6.3, fixed in commit 5b91da5, contains an authorization bypass vulnerability where the executor validates tool calls against the full tool registry rather than the per-request narrowed tool advertisement enforced by ToolBindingMiddleware, allowing owner-only state-changing tools such as wallet transfer, posting, memory-write, and call-agent to execute without any human-in-the-loop or approval gate. An unauthenticated or public caller in WEB, API, TWITTER, or TELEGRAM contexts can exploit this by supplying the exact de-advertised tool name and arguments via indirect prompt injection or by replaying checkpoint and history data on a reused thread, achieving unauthorized execution of owner-restricted capabilities.
