This flaw allows an attacker to gain privileges or access confidential information for any services listening on localhost ports that are not protected by authentication. (CVE-2020-8558)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
