CyberRota Analysis
AI-GeneratedWallos versions prior to 5.0.0 are vulnerable due to a lack of server-side SSRF validation, allowing authenticated users to store arbitrary SMTP hosts, including private IP addresses, in their email notification settings. This flaw enables low-privileged attackers to exploit the server's outbound TCP connections, potentially probing internal network services. Organizations using Wallos should prioritize upgrading to version 5.0.0 to mitigate this risk.

Original NVD Description
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 5.0.0, Wallos lets any authenticated user store an arbitrary SMTP host — including private and cloud-metadata IP addresses — in their personal email notification settings, with no server-side SSRF validation. When the scheduled notification cron job runs, it passes the stored host directly to PHPMailer, causing the Wallos server to open an outbound TCP connection to whatever address the attacker specified. This gives a low-privileged attacker a reliable mechanism to probe internal network services from the server's perspective. This issue has been patched in version 5.0.0.
