Description
Nging through 5.3.5 contains an information disclosure vulnerability that allows any authenticated backend user to list host directories by abusing the public-tagged /user/autocomplete_path endpoint. Low-privileged users without file-manager permission can supply arbitrary paths in the query parameter to enumerate directories readable by the Nging process and confirm specific files exist.
