CyberRota Analysis

AI-Generated

The vulnerability in HomeBox allows self-registered users to exploit improper authorization in the HandleWipeInventory function, enabling them to delete the entire inventory of any group they belong to by manipulating the X-Tenant request header. This results in permanent data loss, as the deleted inventory cannot be recovered without external backups. Organizations using versions prior to 0.26.0 should prioritize updating to the latest version to mitigate this high-severity risk.

Original 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.
