CVE-2026-119598 Details
Description
Miaomiaowu before 0.9.3 contains an insecure direct object reference vulnerability in /api/user/proxy-provider-configs that allows authenticated users to read other users' configurations. Attackers can iterate the global auto-increment external_subscription_id parameter to disclose override scripts, filter rules, custom request headers and health-check URLs.
A cross-user insecure direct object reference vulnerability has been identified in Miaomiaowu versions prior to 0.9.3. This vulnerability allows authenticated users to access and read other users' proxy provider configurations through the '/api/user/proxy-provider-configs' endpoint. The issue arises because the 'external_subscription_id' parameter, which is a global auto-incrementing identifier, can be manipulated to disclose sensitive configuration details such as override scripts, filter rules, custom request headers, and health-check URLs.
Users can update to Miaomiaowu version 0.9.3 or later, where this vulnerability has been fixed.
