Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.9.6, POST /endpoints/notifications/testemailnotifications.php accepts smtpaddress and smtpport from POST body with zero SSRF validation. PHPMailer connects to attacker-supplied host:port. Every other notification endpoint uses ssrf_helper.php but email was missed. Any authenticated user can probe internal network, cloud metadata. This issue has been patched in version 4.9.6.
