During March 2026, contributed to the PrestaShop/docs repository by developing a Safe HTML Rendering Twig extension focused on security-hardening template rendering. This work introduced a dedicated raw_purifier extension that centralized HTML sanitization, addressing XSS vulnerabilities and improving maintainability across the codebase. The implementation leveraged HTML and Twig, applying front end development and security best practices to ensure that raw HTML could be safely rendered within templates. By encapsulating sanitization logic in a single extension, the approach streamlined template security and reduced the risk of inconsistent handling. The contribution was delivered as a single feature commit without any bug fixes.
