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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
