NewCVE-2026-59314 (opens in a new tab)How to fix?
Upgrade org.springframework:spring-web to version 7.0.9 or higher.
Overview
org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.
Affected versions of this package are vulnerable to HTTP Response Splitting via the Content-Disposition header when untrusted input is used to construct its value. An attacker can inject malicious characters to break the HTTP header or corrupt the framing of an outbound multipart body by supplying specially crafted file names or values.
Note: This is only exploitable if the application uses non-default or legacy HTTP connectors that do not reject malicious characters in header values, or if untrusted input is used to set the Content-Disposition of a part in an outbound multipart request body.
