You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Walkthrough

A validation block was added to the socialSignInCallback method in WebInteropApp.ts to ensure the urlToOpen parameter is a safe, same-origin HTTP(S) URL before proceeding with redirection. If validation fails, an error is logged and the method exits early, mitigating potential security issues.

Changes

Cohort / File(s)	Change Summary
WebInteropApp URL Validation `src/Templates/Boilerplate/Bit.Boilerplate/src/Client/Boilerplate.Client.Core/Scripts/WebInteropApp.ts`	Added validation in `socialSignInCallback` to check that `urlToOpen` is a same-origin HTTP(S) URL before redirecting.

Poem

A bunny checks the URLs twice,
To stop bad hops and keep things nice.
If origins stray or schemes are wrong,
The code just logs and hops along.

Safe and sound, our web app stays—
Let’s celebrate these secure new ways!
