CVE-2026-85286— HomeBox: Timing Side-Channel in Login Endpoint Allows User Enumeration via Bcrypt Hashing Delay

Quick assessment

Affected
sysadminsmedia homebox
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

HomeBox 是一个家庭库存与组织管理系统。在 0.27.0 版本之前，POST /api/v1/users/login 接口仅在提交的用户名与现有账户匹配时，才会执行密码哈希验证；若用户名不存在，则直接返回响应。尽管两种路径均返回相同的 401 未授权状态码，但处理时间的差异使得未认证的远程攻击者能够区分已注册的邮箱地址；速率限制仅能减少每个时间窗口内的尝试次数。该问题已在 0.27.0 版本中修复。

Vulnerability Title
HomeBox: Timing Side-Channel in Login Endpoint Allows User Enumeration via Bcrypt Hashing Delay
Source: CVE Program / CVE List V5
Vulnerability Description
HomeBox is a home inventory and organization system. Prior to 0.27.0, the POST /api/v1/users/login endpoint performs password-hash verification only when the submitted username matches an existing account, while unknown usernames return immediately. Although both paths return the same 401 unauthorized response, the processing-time discrepancy allows an unauthenticated remote attacker to distinguish registered email addresses; rate limiting only reduces the number of attempts per window. This issue is fixed in version 0.27.0.
