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.

Affected versions

Maven

Package	Vulnerable	Fixed in
org.apache.tomcat:tomcat	`>= 9.0.0.M1, < 9.0.0.M22`	`9.0.0.M22`
org.apache.tomcat:tomcat	`>= 8.5.0, < 8.5.16`	`8.5.16`
org.apache.tomcat:tomcat	`>= 8.0.0.RC1, < 8.0.45`	`8.0.45`
org.apache.tomcat:tomcat	`>= 7.0.41, < 7.0.79`	`7.0.79`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
