What is a potential consequence of a Content Security Policy (CSP) misconfiguration?

A Content Security Policy (CSP) is a critical security feature that helps mitigate risks such as cross-site scripting (XSS) and data injection attacks by allowing web application developers to control resources the user agent is allowed to load for a given page. A misconfiguration of a CSP can lead to significant security vulnerabilities.

For instance, if the policy is overly permissive, it may allow the execution of malicious scripts from untrusted sources, thus compromising the integrity and confidentiality of the application and its users. Alternatively, if the policy is too restrictive, it might unintentionally block legitimate content, thereby disrupting the normal functioning of the application and leading to a negative user experience.

In this context, the correct answer highlights the importance of properly configuring CSP to safeguard against potential security threats, ensuring that only trusted content is accessible and executable within a web application. The consequences of a misconfigured CSP can have serious repercussions, making it essential for developers to carefully implement and review their security policies.
