Description

WordPress Plugin Yoast SEO is prone to a possible remote code execution vulnerability because it fails to sufficiently sanitize user-supplied input. Successful exploitation may allow attackers to execute arbitrary commands with the privileges of the user running the application, to compromise the application or the underlying database, to access or modify data or to compromise a vulnerable system. WordPress Plugin Yoast SEO version 9.1.0 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 9.2.0 or latest
