Title
Capgo - Cross-Organization Account Disruption via SSO Prelink Endpoint
Summary
Capgo before 12.128.2 contains a cross-organization account disruption vulnerability in the SSO prelink endpoint that allows enterprise administrators to delete password identities of users in foreign organizations. Attackers with org.update_settings permission and an active SSO provider can call the prelink-users endpoint to permanently remove email-based authentication for any user matching the provider's email domain, forcing victims to use the attacker's SSO provider or complete password reset recovery.
