Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-639.

Summary

Miaomiaowu before 0.9.3 contains an insecure direct object reference in /api/user/proxy-provider-configs. An authenticated user with low privileges can read other users' configurations by iterating the global auto-increment external_subscription_id parameter, which discloses override scripts, filter rules, custom request headers and health-check URLs. The flaw is an authorization bypass through a user-controlled key (CWE-639). The CVSS 4.0 vector rates it as network-reachable with no user interaction and a low confidentiality impact.
