jquery-validation — Vulnerabilities & Security Advisories 3

jQuery-validation is a JavaScript library used for validating form inputs on web pages. Historically, it has been susceptible to cross-site scripting (XSS) vulnerabilities due to improper input sanitization, allowing attackers to execute malicious scripts in users' browsers. While remote code execution (RCE) and privilege escalation vulnerabilities are less common, the library's three recorded CVEs primarily involve XSS flaws through crafted input validation rules. Security researchers have identified issues where insufficient escaping of user-controlled data could lead to script injection, particularly in configurations that bypass default sanitization. The library's widespread adoption in web applications has made it a frequent target for vulnerability scanning and exploitation attempts.
