CVE-2021-4380 is a critical authorization bypass vulnerability affecting the Pinterest Automatic plugin for WordPress, specifically versions up to and including 1.14.3. Unauthenticated attackers can exploit missing capability checks in the 'wp_pinterest_automatic_parse_request' function and 'process_form.php' script to update arbitrary site options. This allows for the creation of new administrative user accounts or redirection of site visitors, posing a severe risk to site integrity. With a CVSS score of 9.8 (Critical) and an EPSS score indicating high exploitability, the potential impact is significant. While not currently in the KEV catalog or having active Metasploit/ExploitDB exploits, Nuclei templates exist, and the lack of community discussion or media coverage is typical for most CVEs.
