Because images and audio/video are an integral part of a feed, we can not simply strip them.</p> +<p>Since an attacker can not execute code in contrast to mixed active content, but only replace images/audio/video in your feed reader, this is <strong>not considered to be a security issue</strong>. If, for whatever reason (e.g. feed which would allow fishing), this is a security problem for you, contact the specific feed provider and ask him to serve his feed content over HTTPS.</p> +<h3 id="why-dont-you-simply-use-an-https-imageaudiovideo-proxy">Why don't you simply use an HTTPS image/audio/video proxy?</h3> +<p>For the same reason that we can't fix non HTTPS websites: It does not fix the underlying issue, but only silences it. If you are using an image HTTPS proxy, an attacker can simply attack your image proxy since the proxy fetches insecure content. <strong>Even worse</strong>: if your image proxy serves these images from the same domain as your Nextcloud installation, you are <a href="https://www.owasp.org/images/0/03/Mario_Heiderich_OWASP_Sweden_The_image_that_called_me.pdf">vulnerable to XSS via SVG images</a>. In addition, people feel safe when essentially they are not.</p> +<p>Since most people don't understand mixed content and don't have two domains and a standalone server for the image proxy, it is very likely they will choose to host it under the same domain.</p> +<p>Because we care about our users' security and don't want to hide security warnings, we won't fix (aka silence) this issue.</p> +<p>The only fix for this issue is that feed providers serve their content over HTTPS.</p> +<h2 id="i-am-getting-exception-someclass-does-not-exist-errors-in-my-nextcloudlog">I am getting: Exception: Some\Class does not exist errors in my nextcloud.log</h2> +<p>This is very often caused by missing or old files, e.g. by failing to upload all the News app files or errors during installation.
