Cross-site Request Forgery (CSRF) is a security vulnerability that allows attackers to perform unauthorized actions on behalf of authenticated users, primarily targeting state-changing requests like credential updates or fund transfers. This attack, highlighted in OWASP’s Top 10 list of security risks, exploits the trust a site has in a user's browser. While CSRF's prevalence has decreased due to improved security measures in frameworks, it remains a significant threat, particularly in API calls where developers may overlook the need for a CSRF token. Attackers can execute CSRF by embedding malicious links in web pages or emails, and if successful, can cause substantial harm, especially if an administrator is targeted. Remediation involves implementing unique tokens per user session and re-authentication for sensitive actions, although misconceptions persist regarding the adequacy of methods like CAPTCHA and POST request limitations for protection. Tools like Detectify offer automated testing to identify such vulnerabilities in web applications, providing a resource for developers to ensure their security measures are effective.
