Описание
Оригинално описание
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.
