Executive brief
Capgo, a platform for managing app updates, contained a security flaw that allowed unauthorized access to private user information. By exploiting a misconfigured database function, an attacker could view other users' organization memberships, roles, management email addresses, and billing details. This could lead to targeted phishing attacks or the exposure of sensitive business relationships and account statuses.
Technical details
A missing authorization vulnerability (CWE-862) exists in Capgo's backend due to an improperly restricted PostgREST RPC endpoint. While migrations intended to revoke access to the 'get_orgs_v7(userid uuid)' overload from anonymous and authenticated roles, the function remained invokable via the public API. An unauthenticated attacker can provide a victim's UUID in a JSON request body to the /rest/v1/rpc/get_orgs_v7 endpoint. This bypasses the intended no-argument wrapper that was supposed to derive identity from the caller's session, instead returning the specific victim's organization list, roles, management emails, and billing metadata. The issue was addressed in version 12.128.2 by ensuring the private overload is not accessible to public roles.
