CVE-2026-54600: CWE-287: Improper Authentication in ellite Wallos
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.

Technical Analysis
CVE-2026-54600 describes an improper authentication vulnerability (CWE-287) in Wallos before version 4.9.4. The endpoint endpoints/db/import.php did not enforce authentication and only checked if the user table row count was zero to allow database import. This allowed an unauthenticated attacker on a fresh or unconfigured installation to replace the entire database. The issue is patched in version 4.9.4.
Potential Impact
An unauthenticated attacker can replace the entire database on a fresh or unconfigured Wallos installation by exploiting the lack of authentication on the import.php endpoint. This could lead to complete data loss or unauthorized data manipulation.
Mitigation Recommendations
Upgrade Wallos to version 4.9.4 or later, where this authentication issue has been fixed. No other mitigation is indicated.
