Description

The CORS Filter in Apache Tomcat 9.0.0.M1 to 9.0.0.M21, 8.5.0 to 8.5.15, 8.0.0.RC1 to 8.0.44 and 7.0.41 to 7.0.78 did not add an HTTP Vary header indicating that the response varies depending on Origin. This permitted client and server side cache poisoning in some circumstances.
A vulnerability was discovered in Tomcat where the CORS Filter did not send a "Vary: Origin" HTTP header. This potentially allowed sensitive data to be leaked to other visitors through both client-side and server-side caches.
