There are several things I recommend doing as a developer to try and stop XSS from occurring:
That looks like a XSS pen testing injection to me.
XSS
I believe it is 27 by Medieval Roman numerologyImproved Answer:-In Roman numerals X = 10 and S = 1/2So XSS = 10+1/2+1/2 = 11
XSS Here's a sample attack: alert('Dear WikiAnswers User, you should visit my phishing site and enter all your personal information so that I can steal your identity and clean out your bank accounts. Or maybe I will just show you nasty pictures.'); On certain sites, entering this will cause a popup. WikiAnswers' software is protected from these XSS attacks.

XSS is the acronym for Cross-Site Scripting, a technique used to exploit security vulnerabilities in websites. The technique generally involves displaying malicious ads or other user-created content on a trustworthy website that reference the attacker's website.
In an XSS (Cross-Site Scripting) attack, attackers typically use scripts, such as JavaScript, to inject malicious code into web pages viewed by users. Common targets include input fields, URL parameters, and cookies. However, server-side code, such as PHP or Python scripts executed on the server, cannot be directly used in an XSS attack, as they run on the server rather than in the user's browser.
Cross-Site Scripting (XSS) attacks are unique because they specifically target web applications by injecting malicious scripts into content that is then executed in the browser of unsuspecting users. Unlike other injection attacks, such as SQL injection, which primarily aim to manipulate backend databases, XSS exploits the trust that a user's browser has in a particular website. This allows attackers to steal session cookies, redirect users, or perform actions on behalf of the user, leveraging the user's own permissions. The impact of XSS is often more focused on user interaction and data theft rather than direct database manipulation.

Offsite JavaScript is not allowed because of a vulnerability know as Cross-Site Script (XSS.) XSS happens when user input is improperly filtered, and <script> tags are allowed through to the user as source code. By inserting JavaScript into a site, an attacker can gain access to information given by that site's users. Furthermore, JavaScript can be used to either divert the user to a different page, or to convince the user that a file being downloaded is from a trusted source. See the related links for a complete explanation of XSS and how it is avoided by web programmers.

Securing PHP web applications against common vulnerabilities is crucial for protecting sensitive data and maintaining user trust. Here are some best practices for securing PHP web applications against SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF)
