2. Security improvements
The upgrade introduces fixes for the known security vulnerabilities in the platform, making it secure against potential threats.
- Require.js Update: The platform updates Require.js to version 2.3.7, which fixes security issues like arbitrary code execution and Denial of Service (DoS) attacks.

3. GraphQL Improvements:
Magento 2.4.8 enhances GraphQL capabilities, focusing on performance and extending flexibility:
- Custom Scalar Types Support – Developers can now put an end to their fight with inflexible data structures. GraphQL’s custom scalar types, which were introduced in Magento 2.4.8, enable easy processing of HTML, URLs, and custom data formats. This means less trouble integrating with different services since complicated data structures do not need to be shoehorned into inflexible boxes.
- Pagination Fix for GraphQL Cart Items – Resolves issues with incorrect pagination, ensuring accurate data retrieval for cart items.
- Cache Invalidation for GraphQL Resolvers – Ensures data consistency by properly invalidating the cache when customer data is updated through imports.
- Improved Product Sorting in GraphQL – Allows reliable multi-field sorting in GraphQL queries, aligning results with specified criteria.
4. Rest API Updates:
Product SKU slashes and transaction mistakes have been a quiet issue for long enough. Magento 2.4.8 ends these REST API irregularities with more uniform data exchanges.
