CVE-2026-45577
Neotoma: Unauthenticated Inspector/API access via reverse-proxy loopback auth bypass
Description
Neotoma provides versioned records that persist across agent runs. From 0.6.0 to before 0.11.1, Neotoma can treat public reverse-proxied requests as local when the app receives them over a loopback socket and no Bearer token is present. In affected deployments, the REST auth middleware can resolve unauthenticated requests as the local development user, making the hosted Inspector and related API surface reachable without credentials. This vulnerability is fixed in 0.11.1.

Action Type Old Value New Value Added Translation Title: Neotoma de markmhendrickson, Description: Neotoma proporciona registros versionados que persisten entre ejecuciones de agentes. Desde la versión 0.6.0 hasta antes de la 0.11.1, Neotoma puede tratar las solicitudes públicas con proxy inverso como locales cuando la aplicación las recibe a través de un socket de bucle invertido y no hay un token Bearer presente. En implementaciones afectadas, el middleware de autenticación REST puede resolver solicitudes no autenticadas como el usuario de desarrollo local, haciendo que el Inspector alojado y la superficie de la API relacionada sean accesibles sin credenciales. Esta vulnerabilidad está corregida en la versión 0.11.1. -
