Neotoma: Unauthenticated Inspector/API access via reverse-proxy loopback auth bypass

Published May 29, 2026 · Updated May 29, 2026 · Assigned by GitHub_M

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.
