In jetty-webapp, WebInfConfiguration.makeTempDirectory and cloneConfigure both create the webapp temporary directory with java.nio.file.Files.createTempDirectory, which creates it atomically with owner-only permissions and leaves no window for a local user on a shared /tmp to hijack the directory into which the war and its WEB-INF/lib jars are unpacked. The fix was applied by the upstream Jetty vendor in 9.4.33.v20201020 (October 2020), and this version inherits it from upstream.",
