Executive Summary

CVE-2026-40987 is a vulnerability in Spring Integration's remote-file synchronizer that allows a malicious or compromised FTP, SFTP, or SMB server to write arbitrary files anywhere on the client's filesystem, outside the configured local directory.

This happens because the synchronizer writes server-supplied filenames without proper canonicalization, enabling an attacker to control the file paths and content written on the client system.

The affected versions include Spring Integration 7.0.0 through 7.0.4, 6.5.0 through 6.5.8, 6.4.0 through 6.4.11, 6.3.0 through 6.3.14, and 5.5.0 through 5.5.20.

Impact Analysis

This vulnerability can allow an attacker controlling a remote FTP/SFTP/SMB server to write arbitrary files anywhere on the client filesystem.

Such unauthorized file writes can lead to potential compromise of the client system, including overwriting critical files, injecting malicious code, or disrupting normal operations.

Because the attacker controls the content and location of the files, this can result in integrity and availability impacts on the affected system.

Mitigation Strategies

The primary immediate step to mitigate this vulnerability is to upgrade Spring Integration to one of the fixed versions.

  • Upgrade to version 5.5.21 (Enterprise Support Only)
  • Upgrade to version 6.3.15 (Enterprise Support Only)
  • Upgrade to version 6.4.12 (Enterprise Support Only)
  • Upgrade to version 6.5.8.1 (Enterprise Support Only) or 6.5.9 (OSS)
  • Upgrade to version 7.0.4.1 (Enterprise Support Only) or 7.0.5 (OSS)

No additional mitigation steps are required after upgrading.
