CVE-2021-44223
8.1
CVSS:3.1/AC:H/AV:N/A:H/C:H/I:H/PR:N/S:U/UI:N
Summary
WordPress before 5.8 lacks support for the Update URI plugin header. This makes it easier for remote attackers to execute arbitrary code via a supply-chain attack against WordPress installations that use any plugin for which the slug satisfies the naming constraints of the WordPress.org Plugin Directory but is not yet present in that directory.
