Description Christopher Walker CLA 2021-03-23 08:14:53 EDT 
In Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp, inadvertently serving the webapps themselves and anything else that might be in that directory.

Workaround: Do not use symlinks for Webapp directory

CWEs
CWE-200
