Eclipse Vert.x StaticHandler flaw: hidden dirs not blocked v4.0.0-5.0.4
CVE-2025-11965 Published on October 22, 2025
In Eclipse Vert.x versions [4.0.0, 4.5.21] and [5.0.0, 5.0.4], a StaticHandler configuration for restricting access to hidden files fails to restrict access to hidden directories, allowing unauthorized users to retrieve files within them (e.g. '.git/config').
Weakness Type
Files or Directories Accessible to External Parties
The product makes files or directories accessible to unauthorized actors, even though they should not be. Web servers, FTP servers, and similar servers may store a set of files underneath a "root" directory that is accessible to the server's users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories.
