When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0
to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker
could perform a session fixation attack. The window was considered too
narrow for an exploit to be practical but, erring on the side of caution,
this issue has been treated as a security vulnerability.
