Developed and delivered a new Content Security Policy Vimeo integration preset for the spatie/laravel-csp repository, enabling secure and compliant embedding of Vimeo content within Laravel applications. The work involved creating a dedicated Vimeo class that defines the necessary CSP directives, updating unit tests to validate correct enforcement, and revising documentation to guide developers in adopting the new preset. By focusing on backend development and leveraging PHP and Laravel, the solution reduces the risk of CSP misconfigurations and streamlines the process of configuring external media sources. No major bugs were addressed, reflecting a stable codebase and a targeted feature-driven contribution.
