🔒 Fix: Insufficient Input Validation on Transaction Quantity#41alfieprojectsdev wants to merge 1 commit into
Conversation
- Created `validateTransaction` utility to enforce quantity and batch ID constraints. - Integrated validation into `useInventory` hook to prevent database corruption. - Added UI-level validation in `TransactionForm` for immediate user feedback. - Hardened RxDB schema with `minimum`, `maximum`, and `multipleOf` constraints on `qty`. - Incremented transaction schema version and added identity migration strategy. Fixes a security vulnerability where insufficient input validation could lead to data corruption or malicious input.

This PR addresses a security vulnerability related to insufficient input validation on transaction quantities in the inventory management system.
🎯 What
The
addTransactionfunction in theuseInventoryhook was accepting quantities without validating if they were non-zero, finite, or within reasonable bounds. This could allow for accidental or malicious data corruption.Without proper validation, the system could record invalid transactions (e.g., zero quantity, NaN, or extremely large values) that would corrupt the calculated stock levels and compromise the integrity of the pharmaceutical logistics grid.
🛡️ Solution
The fix implements a multi-layered validation strategy:
validateTransactionfunction enforces that quantities are finite, non-zero integers within the range of [-100,000, 100,000], and that batch IDs are valid.useInventoryhook now validates all transactions before insertion.TransactionFormprovides real-time feedback and prevents submission of invalid data.Verified with manual test scripts for the validation logic.
