Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Neotoma是Mark Hendrickson个人开发者的一个跨工具持久化AI代理状态与记录的本地优先开源工具。 Neotoma 0.6.0至0.11.1之前版本存在访问控制错误漏洞，该漏洞源于应用通过回环套接字接收请求且无Bearer令牌时将公共反向代理请求视为本地请求，可能导致REST认证中间件将未认证请求解析为本地开发用户。

Vulnerability Title
Neotoma: Unauthenticated Inspector/API access via reverse-proxy loopback auth bypass
Source: CVE Program / CVE List V5
Vulnerability 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.
