As of my knowledge cutoff date in September 2021, SonarQube does not provide built-in configuration settings to enable Cross-Origin Resource Sharing (CORS) directly within the application. CORS settings are typically managed at the web server level or through reverse proxy configurations.

If you want to enable CORS for SonarQube, you'll need to configure your web server or reverse proxy to add the necessary CORS headers to the SonarQube responses. The specific steps may vary depending on the web server or reverse proxy you are using. Below are some general guidelines for popular web servers:

  1. Apache: If you are using Apache HTTP Server, you can enable CORS by adding the following lines to your Apache configuration file (e.g., httpd.conf or a virtual host configuration file):

    <IfModule mod_headers.c> Header set Access-Control-Allow-Origin "*" Header set Access-Control-Allow-Methods "GET, POST, OPTIONS, HEAD" Header set Access-Control-Allow-Headers "Authorization, Content-Type" </IfModule>

    The Access-Control-Allow-Origin header is set to "*" to allow requests from any origin. You can replace * with specific domains if you want to restrict CORS to certain origins.

  2. Nginx: For Nginx, you can add the following configuration within the server block:

    server { # Other server configuration... location / { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, HEAD'; add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type'; } }

    As with Apache, you can adjust the Access-Control-Allow-Origin header to control which origins are allowed.

Remember that enabling CORS with a wildcard "*" may not be the most secure option for a production environment. You should restrict the allowed origins to only those domains that need to access the SonarQube server.

After making the necessary configuration changes in your web server, restart the server to apply the new CORS settings. Requests from web clients, including those using JavaScript from different domains, should now be able to access SonarQube resources.

Please note that if SonarQube introduces new features or changes related to CORS after my knowledge cutoff date, it's always a good idea to refer to the official SonarQube documentation or release notes for the most up-to-date information on enabling CORS.
