  "details": "### Impact\nWhen running on servers that are configured to accept a wildcard as a hostname (i.e. the server routes any request, regardless of the HOST header to an October CMS instance) the potential exists for Host Header Poisoning attacks to succeed. See the following resources for more information on Host Header Poisoning:\n- https://portswigger.net/web-security/host-header\n- https://dzone.com/articles/what-is-a-host-header-attack\n\n### Patches\n\nA feature has been added in v1.1.2 to allow a set of trusted hosts to be specified in the application.\n\n### Workarounds\n\n- Apply https://github.com/octobercms/library/commit/f86fcbcd066d6f8b939e8fe897409d152b11c3c6 \u0026 https://github.com/octobercms/october/commit/f638d3f78cfe91d7f6658820f9d5e424306a3db0 to your installation manually if unable to upgrade to v1.1.2.\n\n- Check that the configuration setting `cms.linkPolicy` is set to `force`.\n\n### Alternative Workaround\n\nCheck to make sure that your web server does not accept any hostname when serving your web application.\n\n1. Add an entry called `testing.tld` to your computer\u0027s host file and direct it to your server\u0027s IP address\n2. Open the address `testing.tld` in your web browser\n3. Make sure an October CMS website is not available at this address\n\nIf an October CMS website is returned, configure your webserver to only allow known hostnames. If you require assistance with this, please contact your server administrator.\n\n### References\n\nReported by [Abdullah Hussam](https://github.com/ahussam)\n\n### For More Information\n\nIf you have any questions or comments about this advisory:\n* Email us at [hello@octobercms.com](mailto:hello@octobercms.com)\n\n### Threat Assessment\n\u003cimg width=\"1108\" alt=\"Screen Shot 2021-01-15 at 4 12 57 PM\" src=\"https://user-images.githubusercontent.com/7253840/104783859-92fb3600-574c-11eb-9e21-c0dc05d230a9.png\"\u003e",
