Summary
Capgo before 12.128.2 contains an information disclosure vulnerability in the public.exist_app_v2 RPC function that allows unauthenticated attackers to enumerate app_ids by calling POST /rest/v1/rpc/exist_app_v2 with arbitrary appid parameters.
Risk Assessment
Remote attackers can exploit this SECURITY DEFINER function to determine whether specific app_ids exist in the public.apps table, enabling cross-tenant app enumeration and privacy violations.
Recommendation
It is recommended to upgrade to Capgo version 12.128.2 or later to mitigate this vulnerability and to restrict access to the RPC function for unauthorized users.
