CVE-2026-43975 Details
Description
FolderUploadsFileManager in Apache Wicket does not validate or sanitize the uploadFieldId parameter or the clientFileName before constructing file paths, allowing an unauthenticated attacker to write arbitrary files outside the intended upload directory or read files from arbitrary locations on the server. This issue affects Apache Wicket: from 8.0.0 through 8.17.0, from 9.0.0 through 9.22.0, from 10.0.0 through 10.8.0. Users are recommended to upgrade to version 10.9.0, which fixes the issue.
A vulnerability in the FolderUploadsFileManager component of Apache Wicket allows for path traversal attacks. The issue arises because the uploadFieldId parameter and clientFileName are not properly validated or sanitized before file paths are constructed. This flaw enables an unauthenticated attacker to write arbitrary files outside the designated upload directory or read files from any location on the server. The vulnerability affects Apache Wicket versions 8.0.0 through 8.17.0, 9.0.0 through 9.22.0, and 10.0.0 through 10.8.0.
Users are advised to upgrade to Apache Wicket version 10.9.0, which addresses this vulnerability. For those on Wicket 9.x, additional guidance may be needed, as Wicket 10.0 requires Jakarta J2EE.
