Auth bypass in Ellite Wallos

CVE-2026-54600

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.9.4, endpoints/db/import.php has no authentication. The only guard is a user-table row count — if zero (fresh/unconfigured install), an unauthenticated attacker can replace the entire database. This issue has been patched in version 4.9.4.
