Laravel Backpack CRUD: CRUD panel query scopes are not enforced on Update, Delete, and Reorder (cross-tenant IDOR)
Summary
Backpack CRUD's list and read operations correctly apply any query scopes
registered via addClause() / addBaseClause() (e.g. tenant isolation, user
ownership). However, the Update, Delete, and Reorder operations
bypassed these scopes, fetching records directly from the unscoped model query.
An authenticated user who knows or can guess a record's primary key could therefore update, delete, or reorder records that should be invisible to them — a classic IDOR on write paths.
Applications that rely on addBaseClause for row-level access control
(multi-tenancy, per-user data isolation) are affected.
Impact
Any Backpack CRUD panel that uses addBaseClause or addClause to restrict
which rows a user may access is affected on its write operations.
An authenticated low-privilege user can modify or delete records belonging to
other tenants / users.
Patches
Apply the fixed release for your major version:
- v6: upgrade to 6.8.14 or later
- v7: upgrade to 7.0.38 or later
The fix ensures Update, Delete, and Reorder all resolve records through the same scoped query used by the read side.
Workarounds
If you cannot upgrade immediately, add explicit Gate / Policy checks in your
CrudController's update(), destroy(), and reorder() methods to verify
the authenticated user is permitted to act on the resolved record.
