CVE-2026-85287: HomeBox account lockout via email case sensitivity bypass

CVE-2026-85287 · Severity: medium · CVSS 6.5 · Published 2026-11-05

HomeBox is a home inventory management application that allows users to track and organize household items. Prior to version 0.27.0, an attacker could register an account using a different capitalization of an existing user's email address, which bypasses email uniqueness checks while breaking login for both the attacker's duplicate account and the legitimate user. This denial of service attack allows account takeover by locking out legitimate users from their accounts.

How to fix

Fixed in: 0.27.0

Technical details

The vulnerability stems from inconsistent email handling: the user registration and database uniqueness constraint treat email addresses as case-sensitive, while the login lookup uses case-insensitive comparison. An unauthenticated attacker can exploit this by registering a variant of a victim's email (e.g., "user@example.com" vs "User@example.com"), creating duplicate database rows that cause login authentication to fail with 401 for all variants. The fix normalizes email case handling throughout the application to prevent duplicate accounts.
