Vulnerability Title
Capgo - Account Merge via Poisoned public.users.email in SSO Provisioning
Source: CVE Program / CVE List V5
Vulnerability Description
Capgo before 12.128.12 allows authenticated users to modify their mutable public.users.email to arbitrary addresses, which the SSO provisioning endpoint trusts as an account-merge key. Attackers can pre-position their account with a victim's corporate SSO email, causing the provision-user endpoint to merge the victim's SSO identity into the attacker-controlled account.
