Name of the Vulnerable Software and Affected Versions: Koa versions prior to 2.16.1 Koa versions prior to 3.0.0-alpha.5

Description: The issue arises when passing untrusted user input to ctx.redirect(), which can execute JavaScript code on the user's device, even after sanitizing the input.

Recommendations: For versions prior to 2.16.1, update to version 2.16.1 or later. For versions prior to 3.0.0-alpha.5, update to version 3.0.0-alpha.5 or later. As a temporary workaround, consider avoiding the use of ctx.redirect() with untrusted user input until a patch is applied.
