VetorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions: GNU Wget versions prior to 1.20.1
Description: The issue is related to the set file metadata function in xattr.c of GNU Wget, which lacks protection of metadata. This allows a local user to obtain sensitive information, such as credentials contained in a URL, by reading the user.xdg.origin.url metadata attribute of a downloaded file. Additionally, Referer information in the user.xdg.referrer.url metadata attribute is also accessible.
Recommendations: For GNU Wget versions prior to 1.20.1, update to version 1.20.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the user.xdg.origin.url and user.xdg.referrer.url metadata attributes to minimize the risk of exploitation.
