I'm working on my first serious project and I need some guidance on protecting it from script injection attacks. Any tips or best practices would be greatly appreciated!

Are you specifically worried about XSS attacks? Depending on the tech stack you're using, there are usually built-in tools to escape potentially harmful content. Just search for your framework followed by 'escaping' or 'XSS'. And definitely add a CSP header for an added layer of security! Here’s a good resource to check out: https://developer.mozilla.org/en-US/docs/Web/HTTP/Gudes/CSP.
Protecting against script injection can be tricky but it's vital. First off, sanitizing user inputs is key to preventing SQL injection. Also, to block scripts on the frontend, consider setting up a Content Security Policy (CSP) in your server configuration. Additionally, when using frontend frameworks, it's crucial to avoid rendering HTML or SVGs from outside your codebase. Essentially, the methods to prevent script injection are varied, just like the ways attacks can occur. Good luck with your project!
I’m actually building something like an imageboard, so I need to allow certain content.
