What is CVE-2021-42136?

A stored Cross-Site Scripting (XSS) vulnerability exists in the Missing Data Codes feature of REDCap prior to version 11.4.0. This flaw enables attackers to inject malicious JavaScript code that is stored as a Missing Data Code value. Once the code is executed in the client's browser, it can facilitate a Cross-Site Request Forgery (CSRF) attack, potentially allowing the attacker to escalate privileges to an administrator level. Such vulnerabilities pose significant risks to sensitive data and user integrity.
