CVE-2026-56308 | THREATINT

Description

Capgo before 12.128.2 allows email address changes without requiring current password re-authentication or verification of the existing email address. An attacker with access to a valid session cookie or authenticated browser can change the account email to gain control of account recovery and bypass multi-factor authentication protections.
