Clotaire developed a Safe HTML Rendering Twig extension for the PrestaShop/docs repository, focusing on security-hardening through template sanitization. By introducing the raw_purifier extension, Clotaire centralized HTML sanitization within Twig templates, directly addressing XSS vulnerabilities and improving the maintainability of template code. The solution leveraged HTML and Twig, applying front end development skills and security best practices to ensure that raw HTML could be rendered safely in documentation templates. Although the work spanned a single feature over one month, it demonstrated a targeted approach to mitigating security risks and contributed a dedicated, reusable extension to the project’s codebase.
