Official description
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, testwebhooknotifications.php does not validate the target URL against private/reserved IP ranges, enabling full-read SSRF. The server response is returned to the caller. This issue has been patched in version 4.6.2.
