CVE-2026-45577

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

State: Published
Severity: 6.9 Medium
Published: May 29, 2026
Updated: May 29, 2026
Reserved: May 12, 2026

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.
