K000161019: NGINX ngx_http_rewrite_module vulnerability CVE-2026-42945 needs immediate review anywhere rewrite rules are doing request handling in front of applications, APIs, or login flows. If your stack depends on complex `rewrite`, `if`, `return`, or URI normalization behavior, this is the place to check first. The good news is that the issue is usually manageable with a clear audit, a temporary ruleset cleanup, and a controlled NGINX update.

For most operators, the practical question is not whether NGINX is present. It is whether `ngx_http_rewrite_module` is used in a way that lets crafted requests bypass intended routing or security logic. That distinction matters. A plain static site with minimal config is a very different risk profile from a multi-tenant app gateway with legacy rewrite chains and a few heroic regexes written at 2 a.m.

You open your website and instead of content you see a blank page that says 502 Bad Gateway. It looks scary, but in most cases the fix is straightforward. Let's break down what's happening and how to get your site back.

Want to redirect users and search engines to a new website address? 301 redirect is your best friend! It helps you maintain SEO rankings and avoid 404 errors. In this article, we will show you how to set up 301 redirect in .htaccess and Nginx quickly and easily.

Modern HTTP/2 and HTTP/3 protocols can significantly speed up site loading, improve user experience and increase search engine rankings. But not everything is so simple: they have both advantages and disadvantages. Let's understand what these protocols are, their pros and cons, and how to enable them on your server.

Search engine bots (crawlers) are special programs that scan websites on the Internet. Search engines need them to find, index and display pages in search results. But not all bots are useful!

Sometimes your site may be visited by unwanted bots that:

• Collect data without your permission.
• Consume server resources, slowing it down.
• Are used to look for vulnerabilities.

If you want to protect your site from such bots, it’s time to configure Nginx! In this article, we’ll show you how to easily and quickly block them using a special configuration file.
