Capgo before 12.128.2 contains an information disclosure vulnerability in the public.existappv2 RPC function that allows unauthenticated attackers to enumerate appids by calling POST /rest/v1/rpc/existappv2 with arbitrary appid parameters. Remote attackers can exploit this SECURITY DEFINER function to determine whether specific appids exist in the public.apps table, enabling cross-tenant app enumeration and privacy violations.
