CVE-2026-61638Wallos: SSRF via Test Email Notification - unvalidated SMTP host/port

Updated under an hour ago ()

Does this affect you?

It affects ellite Wallos. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
