While this is generally more secure, it means that any resource types without explicit directives will now be restricted to same-origin only. Missing explicit directives that may be needed: - `worker-src` - for web workers (if used) - `manifest-src` - for web app manifests (if used) - `child-src` - for workers and nested browsing contexts (deprecated but may be needed for compatibility) Please verify that the application doesn't use any resource types that aren't covered by the explicit directives now defined (script-src, connect-src, frame-src, style-src, img-src, font-src, media-src, object-src). Without the broader `default-src` fallback, these resources will be blocked. ########## .htaccess: ########## @@ -1,13 +1,17 @@ ErrorDocument 404 /404.html <IfModule mod_headers.c> - Header always set Content-Security-Policy "default-src 'self' https: data: 'unsafe-inline'; \ - frame-src 'self' https://www.youtube.com https://player.bilibili.com https://hcaptcha.com https://*.hcaptcha.com; \ - script-src 'self' 'unsafe-inline' 'unsafe-eval' https://*.algolianet.com https://*.algolia.net https://*.algolia.io https://api.github.com https://kapa-widget-proxy-la7dkmplpq-uc.a.run.app https://hcaptcha.com https://*.hcaptcha.com; \ + Header always set Content-Security-Policy "default-src 'self'; \ + script-src 'self' 'unsafe-inline' 'unsafe-eval' https://*.algolianet.com https://*.algolia.net https://*.algolia.io https://api.github.com https://kapa-widget-proxy-la7dkmplpq-uc.a.run.app https://js.hcaptcha.com https://*.hcaptcha.com; \ connect-src 'self' https://*.algolianet.com https://*.algolia.net https://*.algolia.io https://api.github.com https://kapa-widget-proxy-la7dkmplpq-uc.a.run.app https://*.hcaptcha.com; \ - style-src 'self' 'unsafe-inline' https://hcaptcha.com https://*.hcaptcha.com; \ - img-src 'self' data: https://hcaptcha.com https://*.hcaptcha.com; \ - frame-ancestors 'self'; \ + frame-src 'self' https://www.youtube.com https://player.bilibili.com https://*.hcaptcha.com; \ + style-src 'self' 'unsafe-inline' https:; \ + img-src 'self' data: https:; \ Review Comment: The `img-src` directive has been changed from specific hcaptcha domains to a broad `https:` wildcard, which allows loading images from any HTTPS source.

This actually reduces security by allowing resources from any HTTPS source rather than specific trusted domains. While the addition of `base-uri` and `form-action` directives does improve security in those specific areas, and tightening `default-src` is generally good, the overall net effect may not be a security enhancement due to the loosened resource directives.
