Apache Struts 2.x before 2.3.25 does not sanitize text in the Locale object constructed by I18NInterceptor, which might allow remote attackers to conduct cross-site scripting (XSS) attacks via unspecified vectors involving language display.

Apache Struts 2.0.0 through 2.3.x before 2.3.20 uses predictable <s:token/> values, which allows remote attackers to bypass the CSRF protection mechanism.

Apache Struts 2.0.0 through 2.3.15.1 allows remote attackers to bypass access controls via a crafted action: prefix.

Multiple open redirect vulnerabilities in Apache Struts 2.0.0 through 2.3.15 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in a parameter using the (1) redirect: or (2) redirectAction: prefix.
