Security Headers
same-origin
Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.
accelerometer=(),camera=(),clipboard-read=(),clipboard-write=(),geolocation=(),gyroscope=(),hid=(),magnetometer=(),microphone=(),payment=(),publickey-credentials-get=(),screen-wake-lock=(),serial=(),sync-xhr=(),usb=(),xr-spatial-tracking=*
Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
same-origin
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
max-age=31536000; includeSubDomains; preload
Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.
nosniff
Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.
SAMEORIGIN
Prevents the page from being embedded in iframes, protecting against clickjacking attacks.
1; mode=block
Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.
Issues Found
- •CRITICAL: 'https:' in form-action allows scripts from ANY HTTPS domaincritical
- •Info: 'blob:' URI in child-srcinfo
- •Info: 'blob:' URI in frame-srcinfo
- •Info: 'blob:' URI in worker-srcinfo
- •Insecure HTTP source allowed in form-actionmedium
- •Missing HIGH directive frame-ancestors (Framing control - prevents clickjacking)high
- •Missing HIGH directive object-src (Plugin control - should be 'none')high
- •Missing MEDIUM directive font-src (Font source control)medium
- •RISK: 'blob:' in worker-src allows creation of workers from dynamic blob contentmedium
- •Unsafe eval() execution allowed in script-srchigh
- •Unsafe inline execution allowed in style-srchigh
Recommendations
- →Add font-src directive with appropriate restrictions
- →Add frame-ancestors directive with appropriate restrictions
- →Add object-src directive with appropriate restrictions
- →Consider implementing a stricter Content Security Policy

via OSN, our sister projectSecurity headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
