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.

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability none.
