Thanks, @manishdhorepatil-art, for the PR!

• Is this PR taking a different approach than the existing $_GET['pagenow'] and $_GET['widget'] unsanitized in dashboard AJAX handler #11540 and Ajax: Improve sanitization and screen state in dashboard widget updates. #11661?
• Also, could you explain why wp_unslash() is needed here?

Instead of opening a separate PR, I think it would be better to review the existing PRs and share your thoughts or feedback there. That way, we can avoid reviewing multiple PRs for the same issue if only minor changes are needed.

Thanks for the feedback

my intention was to align the change with the wordpress coding standards by sanitizing request data after calling wp_unslash(), since request superglobals are typically unslashed before sanitization in WordPress.

I understand your point about the existing PRs. rather than maintaining a duplicate PR, I'll review PR #11540 and PR #11661, share my feedback there, and close this PR if it's not needed.
