How to fix?

Upgrade Debian:unstable jetty12 to version 12.0.39-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty12 package and not the jetty12 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

In Eclipse Jetty, TryPathsHandler and TryFilesFilter can be configured to forward requests to template URIs such as index?p=$path, where $path is the request path in context.

However, URI paths may contain characters that are reserved in URI queries so that a path of /s&amp;a=1 when applied to the template becomes index?p=/s&amp;a=1, which is interpreted as 2 query parameters: p=/s and a=1, rather than just one query parameter p whose value is /s&amp;a=1.
