Short explanation

OpenAlgo versions contain an improper certificate validation vulnerability that disables TLS hostname and certificate checks for STARTTLS and SMTPS during SMTP connections. This allows network-positioned attackers to present forged certificates to intercept credentials and mail.

Why does it matter?

Network-positioned attackers can intercept sensitive emails and SMTP credentials, including password-reset links.
