What is CVE-2021-44223?

WordPress versions prior to 5.8 are susceptible to a vulnerability that lacks support for the Update URI plugin header. This loophole can be exploited by remote attackers to execute arbitrary code through a supply-chain attack. The issue arises when WordPress installations utilize plugins that adhere to the naming conventions of the WordPress.org Plugin Directory but have not yet been included in that directory. Consequently, this vulnerability can open the door for unauthorized access and manipulation of affected WordPress sites, emphasizing the importance of vigilant plugin management and adherence to security best practices.
