Veracode has detected that CWE on a static png file because it doesn't include the "x-content-type-options" header. Should it be included? What are the consequences of not including it? Thanks in advance

Hi @APrieto034095 (Community Member) ,
In general we recommend that you apply the "X-Content-Type-Options" header with the "nosniff" header broadly across your domain. In general you should not be relying on 'mime type sniffing' and as such should be able to send this header out for every response. This will automatically close the flaw on rescan.
You can read more on the purpose of this header over on Stack Overflow: https://stackoverflow.com/a/37201425/4512 .
The risk from missing this header is low in general as it is more a defense-in-depth technique, and if the static file is properly administrator controlled an attacker may not be able to modify it. But not having this header on all responses from your application is an indication that it is not globally configured and there may be other, more risky exploit paths that we are unable to see in our Dynamic Analysis.
Thank you,
