Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Drupal Views Builk Operations (VBO) module 6.x-1.0 through 6.x-1.10 does not properly escape the vocabulary help when the vocabulary has had user tagging enabled and the "Modify node taxonomy terms" action is used. A remote attacker could provide a specially-crafted URL that could lead to cross-site scripting (XSS) attack.
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.
