Capgo before 12.128.2 contains an information disclosure vulnerability in the unauthenticated /private/sso/check-domain endpoint that returns internal org_id and provider_id values. Attackers can enumerate email domains to build mappings of domains to organization UUIDs and SSO provider identifiers, enabling reconnaissance against Capgo tenants.
