Review Laravel authorization policies before outsourcing a resource change

Describe permissions without naming policy methods

Write rules in business terms: which actor may perform which action on a resource with a given tenant, owner, and lifecycle state. Include delegated access and archived records. If the rule cannot be stated clearly, a Laravel policy method will only hide the ambiguity. Create synthetic users and records for decisive rows, using identifiers that make tenant substitution obvious.

For each matrix row, name the response and durable effects. A denial means more than a 403. Database changes, events, jobs, exports, notifications, and audit records must remain absent unless the approved design records the denied attempt. This matrix becomes the oracle for HTTP routes, direct service calls, queues, console commands, and bulk endpoints.

Observe what route binding reveals before the policy

Compare a missing identifier, same-tenant forbidden record, and foreign-tenant identifier. Capture status, response shape, logs, and model hooks. Global binding may load another tenant’s row before authorization rejects it. The application should not leak a private title or confirm the record through a different error. Scope nested binding where the route contract supports it.

Binding is not the only control because services and jobs can receive models without the route. Call the operation boundary directly in tests with a foreign-tenant model. Check mass assignment and related-record lookups too. A policy protecting the parent does not automatically constrain every child identifier supplied in the same request.

Mix authority in bulk work, then delay execution

Send one bulk request containing an allowed record, forbidden same-tenant record, foreign-tenant record, and missing identifier. Decide atomic or per-item behavior before implementation. Inspect state and emitted work. A loop that mutates before authorizing the next item can leave partial changes behind. If partial success is approved, each result and retry rule must be explicit.

Dispatch an approved operation, then remove the user’s role or change resource state before the worker runs. Decide whether request-time or execution-time authority governs. Store only the context required for that rule and re-fetch current state. Retry the job to expose duplicate side effects. Exports and notifications require the same actor and tenant discipline.

Review bypasses and audit fields separately

Inspect policy before hooks, administrator shortcuts, scheduled jobs, console commands, and support impersonation. Give each bypass a narrow purpose and test. “Administrator” is not enough when an action crosses tenants or protected data. Emergency access belongs to a separately audited path, not a permissive branch added to make maintenance easier.

Deliver the permission matrix, entry-point inventory, fixtures, request transcripts, denied-effect assertions, mixed bulk outcome, queued timing cases, bypass list, and audit-field review. Avoid copying protected model data into logs. Product and security owners decide ambiguous permissions and exceptions. The programmer makes the approved rule consistent; they do not decide who deserves access.

Test relationships and entry points, not just named roles

Construct a compact authorization lattice using synthetic users: owner, collaborator, same-tenant stranger, other-tenant user, suspended member, and administrator acting through the documented support path. Pair them with ordinary, archived, transferred, and soft-deleted records. Run view, update, delete, restore, and the sensitive custom action through web routes, JSON endpoints, queued commands, and any bulk endpoint that reaches the same model. Record HTTP status, response shape, database change, audit event, and whether the record's existence is revealed. A policy unit test alone can pass while a controller omits authorization or a serializer exposes data before the policy runs. Test list queries too; hiding a detail route does not help if an index returns the same fields. Change tenant membership between queueing and execution to see whether the job trusts stale authorization captured at dispatch.

Probe framework shortcuts that commonly bypass expectations. Route-model binding may resolve a record outside the current tenant before a policy denies it. Mass assignment may accept an ownership field the form never displays. A bulk action may authorize the collection but not every selected row. Signed URLs and cached responses can outlive a membership change. Create one fixture for each boundary and retain the denied result as a control. If administrators have an override, require a named reason and verify its audit record; do not treat a global before hook as self-justifying. Compare browser and API error behavior so one channel does not reveal identifiers the other conceals. Finish with a matrix tied to route names and policy methods, plus a query showing no unauthorized mutation occurred. Product and security owners decide support powers, concealment, and retention. The delegated reviewer supplies reproducible evidence about every entry point, which is far more useful than adding another role check to a controller that happened to fail.

Add a mutation-focused control for indirect changes. An authorized update to a child record must not permit moving it under a parent in another tenant, and a restore action must recheck access to its current parent. Submit stale form data after ownership changes, and test a queued export whose requester loses access before generation or download. Clear policy and query caches between identities so a decision cannot leak from one request to another. Inspect validation errors for private field values, temporary download URLs for scope and expiry, and audit rows for actor, subject, action, and outcome. Run the matrix with the optimized application configuration used in production. This final pass establishes that authorization follows the resource throughout its lifecycle instead of guarding only the first controller method a reviewer happened to inspect.

Include file uploads and exports in the review when they expose protected records. Guess a valid storage key from another tenant, request a thumbnail directly, and reuse an expired temporary link. Export a mixed selection containing one forbidden row and confirm the system rejects or filters it according to an approved rule, with no partial private archive left behind. Verify notification previews, search indexes, and activity feeds apply the same visibility decision as the primary page. Reassign the fixture during an open browser session and repeat cached navigation. These secondary surfaces often escape controller-focused reviews, so their explicit results belong beside the policy matrix and mutation evidence.
