AI-suggested

Upgrade Apache James server to version 3.9.1 or later, which contains the official fix for this vulnerability.

Description

Apache James server versions prior to 3.9.1 contain a path traversal vulnerability in the SieveFileRepository component. This flaw allows authenticated attackers to set arbitrary SIEVE scripts for other users by bypassing file path validation. Exploitation can lead to denial of service or interception of mail traffic. The issue is fixed in version 3.9.1, and users are advised to upgrade.
