Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Cross-organization account disruption in Capgo before 12.128.2 lets an enterprise administrator in one organization destroy the email/password login of users belonging to different organizations. By abusing the SSO prelink-users endpoint, an attacker holding the org.update_settings permission with an active SSO provider can permanently remove password identities for any user whose email matches the provider's domain, locking victims out of native authentication and forcing them onto the attacker's SSO or a password-reset recovery flow. …
