Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring Framework's spring-webmvc and spring-webflux packages are affected in versions 5.2.0 before 5.2.3, 5.1.0 before 5.1.13, and 5.0.0 before 5.0.16. An application is vulnerable when it sets a Content-Disposition response header whose filename comes from user-supplied input, which allows a reflected file download attack. Upgrade to spring-webmvc or spring-webflux 5.2.3, 5.1.13, or 5.0.16, depending on your release line.
