CVE-2024-9589: category and taxonomy meta fields vulnerability

What is known

The Category and Taxonomy Meta Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'new_meta_name' parameter in the 'wpaft_option_page' function in versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with administrator-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Business impact

Successful exploitation of CVE-2024-9589, a medium vulnerability (CVSS 5.5) affecting category and taxonomy meta fields, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether category and taxonomy meta fields is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation.
