CVE-2025-55137Network attack vector

Unauthorized password reset via untyped query fields

Published Aug 7, 2025 · Updated Aug 7, 2025

Type confusion in LinkJoin through 882f196 allows remote attackers to reset account passwords via crafted JSON password-reset fields. The reset_password handler passes unvalidated email and token values into MongoDB queries, allowing JSON objects to act as query operators rather than strings. No authentication or user interaction is required, and successful exploitation changes credentials for an account selected by the injected query conditions, enabling unauthorized access.
