Capgo - Information Disclosure via Unauthenticated RPC Function exist_app_v2

Assigner: VulnCheck
Reserved: 20.06.2026 Published: 24.06.2026 Updated: 24.06.2026

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. 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.
