## Overview

Perspective 5.0.0 contains a path traversal vulnerability that allows unauthenticated remote attackers to read arbitrary files from the server filesystem by including literal ../ segments in HTTP request URL paths. Attackers can bypass the insufficient query-string-stripping sanitization to traverse outside the configured asset root directory and retrieve sensitive files such as system credentials and application secrets, with results exposed cross-origin due to a wildcard Access-Control-Allow-Origin header set on all responses.

## Remediation
