TLS Hostname Verification Flaw in Keycloak by Red Hat

CVE-2020-1758

Summary

A flaw in Keycloak versions prior to 10.0.0 allows attackers to circumvent TLS hostname verification when sending emails via an SMTP server. This oversight can enable a man-in-the-middle (MITM) attack, compromising sensitive email communications and exposing personal information. Proper security measures should be implemented to mitigate the risk of unauthorized intercepts during email transmissions, thus ensuring the integrity and confidentiality of the data.
