CVE-2026-54600: Ellite Wallos

High severity, CVSS 8.2. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Ellite Wallos: before 4.9.4 (fixed in 4.9.4)
