Cross-Site Scripting (XSS)

Cross-site scripting (XSS) is a security vulnerability found in web apps.

Attackers can inject client-side scripts, bypass access controls, and cause various effects, from nuisance to security risk.

XSS accounted for 84% of all security vulnerabilities in 2007.

XXS attacks involve injecting malicious code into a vulnerable website, which is then delivered to the user’s browser and can disrupt services or steal info.
