What is CVE-2026-75599?

HomeBox, a home inventory and organization system, has a flaw in its maybeUrl() utility that allows authenticated users to store javascript: URIs in custom fields without proper validation. This enables malicious users to create clickable links that execute attacker-controlled JavaScript when clicked by other authenticated users. This could lead to session theft, account takeover, or unauthorized data access. The vulnerability has been addressed in version 0.27.0.
