CVE-2026-61638

Name of the Vulnerable Software and Affected Versions Wallos versions prior to 4.9.6

Description An authenticated user can perform Server-Side Request Forgery (SSRF), a flaw where the server is tricked into making requests to an unintended location, allowing the probing of internal networks and cloud metadata. The issue occurs because the endpoint '/endpoints/notifications/testemailnotifications.php' accepts the smtpaddress and smtpport variables from the POST body without validation, causing PHPMailer to connect to an attacker-supplied host and port.

Recommendations Update to version 4.9.6.
