CVE-2026-48975: CWE-639: Authorization Bypass Through User-Controlled Key in sysadminsmedia homebox
HomeBox is a home inventory and organization system. Prior to 0.26.0, MaintenanceEntryRepository.Update and MaintenanceEntryRepository.Delete in backend/internal/data/repo/repo_maintenance_entry.go use UpdateOneID(id) and DeleteOneID(id) without verifying that the maintenance entry belongs to the authenticated user's active group. An authenticated low-privileged user who knows or enumerates another tenant's maintenance-entry UUID can overwrite that record or permanently delete it. This issue is fixed in version 0.26.0.
AI Analysis
Technical Summary
CVE-2026-48975 describes an authorization bypass vulnerability (CWE-639) in sysadminsmedia's HomeBox home inventory system. Specifically, in versions before 0.26.0, the backend functions MaintenanceEntryRepository.Update and MaintenanceEntryRepository.Delete call UpdateOneID(id) and DeleteOneID(id) without verifying that the targeted maintenance entry belongs to the authenticated user's active group. This allows an authenticated user with low privileges who can guess or enumerate another tenant's maintenance-entry UUID to overwrite or delete that tenant's maintenance record. The vulnerability is fixed in version 0.26.0.
Potential Impact
An attacker with valid authentication but low privileges can modify or delete maintenance entries of other tenants, leading to integrity and availability impacts on data. The CVSS 3.1 score is 8.1 (high), reflecting network attack vector, low complexity, low privileges required, no user interaction, unchanged scope, no confidentiality impact, but high integrity and availability impact.
Mitigation Recommendations
Upgrade HomeBox to version 0.26.0 or later, where the issue is fixed by verifying ownership of maintenance entries before update or delete operations. No other mitigations are indicated.
