Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.7.0, the SSRF fix applied in version 4.6.2 for CVE-2026-30839 and CVE-2026-30840 is incomplete. The validate webhook url for ssrf() protection was added to the test* notification endpoints but not to the corresponding save* endpoints. An authenticated user can save an internal/private IP address as a notification URL, and when the cron job sendnotifications.php executes, the request is sent to the internal IP without any SSRF validation. This issue has been patched in version 4.7.0.
