CVE-2026-84177 Nov 1, 2026 Source: Vendor
Incorrect behavior order in Apache Wicket: a file path is validated before the framework appends the attributes that complete it.
org.apache.wicket.request.resource.PackageResource asks the configured package resource guard about a path built from the scope class' package and the file name in the request URL, and then hands that same path to the resource stream locator together with a style, a variation and a locale. Those three attributes are decoded from the name of the first query parameter
