Wallos: SSRF via webhook test endpoint

Assigner: GitHub_M
Reserved: 05.03.2026 Published: 07.03.2026 Updated: 07.03.2026

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.
