CVE-2018-20483 (retired)

Priority
Description
set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's
origin URL in the user.xdg.origin.url metadata attribute of the extended
attributes of the downloaded file, which allows local users to obtain
sensitive information (e.g., credentials contained in the URL) by reading
this attribute, as demonstrated by getfattr. This also applies to Referer
information in the user.xdg.referrer.url metadata attribute. According to
2016-07-22 in the Wget ChangeLog, user.xdg.origin.url was partially based
on the behavior of fwrite_xattr in tool_xattr.c in curl.
