Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
The Translate WordPress with GTranslate WordPress plugin before 2.9.7 does not sanitise and escape the body parameter in the url_addon/gtranslate-email.php file before outputting it back in the page, leading to a Reflected Cross-Site Scripting issue. Note: exploitation of the issue requires knowledge of the NONCE_SALT and NONCE_KEY
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.
