What are the limitations of Content Security Policy (CSP)?

What are the limitations of Content Security Policy (CSP)?

Content Security Policy (CSP) is a powerful security feature, but it has some limitations. For instance, it can't prevent all types of attacks, such as those that exploit vulnerabilities in the browser itself.

Can CSP completely protect my website from XSS attacks?

While CSP can significantly reduce the risk of XSS attacks by controlling resources the browser is allowed to load, it cannot guarantee complete protection. Attackers may still find ways to bypass it.

What happens if I misconfigure my CSP?

Misconfiguring CSP can lead to either overly permissive policies, which may expose your site to attacks, or overly restrictive policies that break legitimate functionality on your site.

Are there any browser compatibility issues with CSP?

Yes, while most modern browsers support CSP, there can be differences in implementation and support for specific directives, which may lead to inconsistent behavior.
