Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The Vert.x Web static handler component cache can be manipulated to deny the access to static files served
 by the handler using specifically crafted request URI. The issue comes from an improper implementation of
 the C. rule of section 5.2.4 of RFC3986 and is fixed in Vert.x Core component (used by Vert.x Web):
 https://github.com/eclipse-vertx/vert.x/pull/5895 Steps to reproduce Given a file served by the static
 handler, craft an URI that introduces a string like bar%2F..%2F after the last / char to deny the access
 to the URI with an HTTP 404 response. For example https://example.com/foo/index.html can be denied with
 https://example.com/foo/bar%2F..%2Findex.html Mitgation Disabling Static Handler cache fixes the issue.
 StaticHandler staticHandler = StaticHandler.create().setCachingEnabled(false); (CVE-2026-1002)
