Apache Tomcat is a servlet container.

protected resource could bypass the Cross-Site Request Forgery (CSRF)
prevention filter. A remote attacker could use this flaw to perform
CSRF attacks against applications that rely on the CSRF prevention
filter and do not contain internal mitigation for CSRF.
