This medium-severity CVE scores 6.9 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
