Published Aug 31, 2026 CVSS 4.0 · 8.2 High EPSS < 1% KEV · Not listed
Description
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.
