**Name of the Vulnerable Software and Affected Versions** Sanic versions prior to 0.5.1 **Description** The issue allows reading arbitrary files with directory traversal. This can be demonstrated by the "/static/..%2f" substring, which showcases the vulnerability in handling directory traversal attacks. **Recommendations** For versions prior to 0.5.1, update to version 0.5.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the `/static/` endpoint to minimize the risk of exploitation.
