Vulnerability Details
Affected area: HasMany / MorphMany relation handling during CRUD create and update operations
CWE: CWE-862 — Missing Authorization
Severity: Medium
CVSS: 6.5 — CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
Summary
Backpack CRUD contained an authorization issue in the way certain HasMany and MorphMany relationship fields were processed during create and update operations.
When an admin form allowed users to manage multiple related records, Backpack could update related model records based on submitted primary keys without sufficiently checking whether those records were eligible to be associated with the current parent model.
This could allow an authenticated, low-privileged admin user to affect related records outside the intended authorization or tenancy boundary, if the affected CRUD form exposed this type of relationship field.
Root Cause
The vulnerable logic processed submitted relationship values and updated matching related records without consistently limiting those updates to records that already belonged to the current parent model, or to records allowed by the developer-defined relation scope.
As a result, a user with permission to edit one parent record could potentially cause unrelated child records to be reassigned, detached, nulled, or deleted as a side effect of saving the form.
This issue is separate from earlier fixes that scoped direct CRUD operations on the main entity. Those protections covered the model being…
