CVE-2021-44223
CRITICAL9.8EPSS 27.5%發布日:2021/11/25修改日:2026/5/27
描述
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.
