Path traversal in Spring Integration - CVE-2026-47862
Published: August 28, 2026
Vulnerability details
The vulnerability allows a remote user to write a .zip archive to an arbitrary filesystem path outside the configured workDirectory.
The vulnerability exists due to improper input validation in ZipTransformer when using the file_name message header to build the workDirectory path. A remote user can set a specially crafted file_name header on a message to write a .zip archive to an arbitrary filesystem path outside the configured workDirectory.
The issue applies when ZipTransformer is used with ZipResultType.FILE, which is the default behavior.
