Improper Access Control, Incorrect Authorization vulnerability in Apache Tomcat leads to security constraint bypass if a constraint for a longer path is specified before a more restrictive constraint for a shorter sub-path.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120, from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109.
