Machine-written summary

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

Spring Framework's spring-web package is vulnerable to reflected file download when an application sets a Content-Disposition header with a non-ASCII charset and derives the filename from user input without sanitizing it. Affected versions are 6.2.0 to 6.2.7, 6.1.0 to 6.1.20, and 6.0.5 to 6.0.28. An attacker must be able to inject malicious content into the downloaded response for the attack to work. Upgrade to 6.2.8 or 6.1.21; for 6.0.x, the fix (6.0.29) is commercial only.
