Which of the following vulnerabilities exploits a user's browser to generate unauthorized commands?

The vulnerability that exploits a user's browser to generate unauthorized commands is cross-site request forgery (CSRF). CSRF takes advantage of the trust that a web application has in the user's browser. When a user is authenticated to a website and unknowingly triggers an action (like changing their email address or transferring funds) by clicking on a malicious link or visiting a forged page, the actions are executed without the user's consent or knowledge. The browser sends the request to the web application, which believes the request is legitimate due to the user's previous authentication.

This particular vulnerability emphasizes the importance of enforcing proper security measures like anti-CSRF tokens, which help verify that the request originated from the legitimate user session. By understanding how CSRF works, security professionals can better protect applications by implementing necessary defenses to mitigate the risk of unauthorized actions performed through a user's browser.
