Insecure or unset HTTP headers - X-Frame Options

Description

Impact

Embed the application in malicious frames.

Recommendation

- Disable the X-Frame Options from the server responses.
- Define the frame_ancestors policy in the Content Security Policy header.

Threat

Anonymous attacker from the Internet.
