CVE-2026-19010 Details
Description
A security vulnerability has been detected in TinyAGI 0.0.20. Impacted is the function processMessage of the file packages/main/src/index.ts of the component Message API Endpoint. Such manipulation leads to missing authorization. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A vulnerability in TinyAGI version 0.0.20 has been identified, where the Message API Endpoint lacks proper authorization. This flaw allows unauthenticated users to send messages that are processed by the Anthropic Claude integration with disabled permission checks, potentially leading to unauthorized execution of privileged actions. The issue arises from the API accepting arbitrary message input, which is then enqueued for agent execution without any validation or risk assessment. When the message is processed, it is forwarded to the Claude CLI with a flag that bypasses normal permission approvals, creating a significant security risk.
