Worked on enhancing the MicrosoftDocs/power-platform repository by delivering security-focused documentation improvements centered on Content Security Policy (CSP) hardening. Focused on updating the admin documentation to clarify and reinforce secureDefaults, the work involved specifying allowed script sources for model-driven apps and updating CSP defaults to include blob: and data: in script-src. These changes, implemented using Markdown and documentation best practices, aimed to improve guidance for both developers and administrators. The updates strengthened the security posture of Power Platform solutions by enabling safer script embedding and reducing the risk of script-based vulnerabilities, while also increasing clarity and usability of the documentation.
