AI risk analysis

Summary: The flaw allows a user to delete another group's inventory by exploiting the global owner privilege through the X-Tenant header, leading to irreversible data loss.
Exploitability: Exploitation requires access to the X-Tenant header and knowledge of another group’s ID, making it moderately difficult but feasible for an attacker with sufficient information.
Blast radius: If exploited, this can result in significant data loss across multiple groups, impacting users who rely on the system for inventory management.
Prioritized remediation: Update to version 0.26.0 or later to apply the necessary authorization fix.

NVD description

HomeBox is a home inventory and organization system. Prior to 0.26.0, HandleWipeInventory in backend/app/api/handlers/v1/v1_ctrl_actions.go authorizes POST /v1/actions/wipe-inventory through the global ctx.User.IsOwner value instead of the caller's role in the active group, while the active group is selected through the X-Tenant request header. Because every self-registered user who creates a group receives the global owner value, a user who is also a member of another group can select that group with X-Tenant and permanently delete its complete inventory, which is not recoverable without external backups. This issue is fixed in version 0.26.0.
