A non-standard but widely accepted header introduced originally by Microsoft to disable "content sniffing" or heuristic content type discovery in absence or mismatch of a proper HTTP
Content-Type declaration, which led to a number of web attacks. In general, presence of the header with its only defined value of
nosniff is considered as part of a properly secured HTTP response.
Fuzzy content type guessing is disabled+1
Controls an Cross-Site Scripting (XSS) filters built into the majority of web browsers. The filter is usually turned on by default anyway, but requirement to set the header to
1 became part of canonical set of "secure" HTTP headers. Over time, vulnerabilities in the "sanitizing" mode filter were found, so
1; mode=block became the recommended value. Some companies decided that they don't really need a browser-side XSS filter to mess with their web services which are XSS-free anyway and they became consciously disabling the XSS filter by setting the header to
XSS auditor is enabled in sanitization mode+1
XmlHttpRequest from a website that is not in the same origin, which is a precaution against various types of data stealing attacks. The target server has to explicitly allow the origin domain using the
Access-Control-Allow-Origin (ACAO) header, or it may allow all origins to access it using a wildcard
*. The latter however creates a potential security issue if the website in question is transactional and processing sensitive data, so the wildcard should be only used on websites consciously offering public APIs.
The header sets permissive AJAX access by using wildcard origin
*. It may be OK if the website is a publicly accessible REST API but otherwise it should be not present at all

X-Frame-Options header is missing
base-uri allows attackers to inject
base tags which override the base URI to an attacker-controlled origin. Set to
'none' unless you need to handle tricky relative URLs scheme
