CVE CVE-2021-44223
CVSS 8.1 (High)
Publicly Published November 25, 2021

Researcher Kamil Vavra

Description

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.
