Summary

IntentKit through 2.6.3 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. 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 in WEB, API, TWITTER, or TELEGRAM contexts can execute owner-restricted capabilities, leading to unauthorized actions and potential losses.

Recommendation

Update IntentKit to a version later than 2.6.3, enforce the narrowed tool set at execution time, and restrict public access to WEB, API, TWITTER, and TELEGRAM contexts.

Original NVD description (English source)

IntentKit through 2.6.3 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.
