Ensure the API is secured against negative quantities

While the UI uses a number input which might prevent negative values, the API should validate input to prevent setting negative quantities which would make no sense for inventory items.

Security Concern: Enforce Non-Negative Quantities in API

The current implementation of the data models (e.g., in backend/internal/data/repo/repo_items.go) shows that the Quantity field is defined as an int without any explicit validation against negative values. Although the UI may restrict input, this leaves the API vulnerable if a negative value is passed directly.

• Issue: No validation is present on the backend to reject negative quantities.
• Recommendation:
  • Add a validation rule (such as validate:"min=0") directly to the JSON binding struct fields (for example in ItemUpdate and other related input structs).
  • Alternatively, include a middleware or business logic check in the API endpoints that handle item creation or update to ensure the quantity is not negative.

This change will strengthen the API’s security posture by ensuring that negative quantities cannot be set, thereby preventing potential discrepancies in inventory data.

15-19: Consider adding input validation constraints

While the field uses type="number", it doesn't have min/max constraints or step validation. According to the PR description, non-integer inputs should be flagged.

 <FormTextField
   v-model="form.quantity"
   :label="$t('components.item.create_modal.item_quantity')"
   type="number"
+  min="1"
+  step="1"
 />

Consider adding input validation for quantity

The Quantity field in the ItemCreate struct does not have any validation constraints. Consider adding validation to ensure that quantity is a positive integer.

Run this script to check how input validation is handled for other fields in the codebase:

Action Required: Add Validation to Quantity Field

It appears that all other fields in the ItemCreate struct already enforce validation rules (for example, the Name and Description fields use tags like validate:"required,min=1,max=255"). However, the Quantity field is missing a similar validation tag to ensure it holds only positive values.

• Proposed Change:
  Update the declaration of the Quantity field in backend/internal/data/repo/repo_items.go (around line 63) to:

      Quantity int `json:"quantity" validate:"min=1"`

  This change enforces that any provided quantity is at least 1 (i.e., a positive integer).

• Security Recommendation:
  Always validate and sanitize user inputs to prevent any unexpected behavior or potential attack vectors. In this case, ensuring that Quantity is non-negative not only upholds business logic but also minimizes risks such as integer underflow/overflow issues.
