What is CVE-2021-38384?

Serverless Offline version 8.0.0 exhibits an improper access control vulnerability that can mislead developers regarding the HTTP status code handling of routes with trailing slashes. While the tool returns a 403 HTTP status, the actual behavior in the AWS environment is a 200 status, suggesting that permissions may be misconfigured and allowing potentially unauthorized access.
