Description

Severity: Low

Content type header is missing.

Example Attack

Injection Attacks: Without the Content-Type header specifying text/html or application/json, browsers or applications can incorrectly interpret response data and Cross-Site Scripting (XSS) can occur. This ambiguity can be exploited by attackers to inject malicious scripts, which execute within the context of other users' sessions, leading to unauthorized actions or data theft.

Remediation

Ensure that the server correctly sets the content-type header for responses.
