CVE-2026-49410 Details
Description
OpenHuman is an open-source agent harness available as a desktop application and Rust library. Versions before 0.56.0 allow cross-site request forgery against the unauthenticated GET /auth/telegram loopback callback because telegram_auth_handler consumes an attacker-supplied one-time Telegram login token and passes the returned JWT to credentials::ops::store_session without validating browser fetch metadata or the request origin. An attacker with an OpenHuman account can cause a user with the local core running to visit a malicious page that requests the /auth/telegram endpoint on loopback port 7788, switching the user's active local session to the attacker's backend account and exposing subsequent agent actions, memory writes, and Telegram messages associated with that session to the attacker. This issue is fixed in version 0.56.0.
A cross-site request forgery (CSRF) vulnerability has been identified in OpenHuman versions prior to 0.56.0. The issue arises in the unauthenticated GET /auth/telegram loopback callback, where an attacker can exploit the telegram_auth_handler by sending a crafted one-time Telegram login token. This token is then used to obtain a JSON Web Token (JWT), which is stored as the user's active local session without proper validation of the request origin or browser fetch metadata. As a result, an attacker with an OpenHuman account can manipulate a user's session, accessing sensitive data and actions associated with that session.
Users should update to OpenHuman version 0.56.0 or later, where this vulnerability has been fixed.
