AI risk analysis

Summary: The flaw allows a user to delete another group's inventory by exploiting the global owner role, leading to data loss.
Exploitability: Exploitation is moderately hard as it requires the attacker to be a member of another group and manipulate the X-Tenant header. Self-registered users are pre-authorized as global owners.
Blast radius: If exploited, the complete inventory of another group can be permanently deleted, impacting multiple users and their data.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 0.26.0 or later.

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.
