Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
The My Tickets WordPress plugin before 1.8.31 does not properly sanitise and escape the Email field of booked tickets before outputting it in the Payment admin dashboard, which could allow unauthenticated users to perform Cross-Site Scripting attacks against admins
CWE-79 - Cross Site Scripting
Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
