CVE-2024-9589: Category and Taxonomy Meta Fields <= 1.0.0 - Authenticated (Administrator+) Stored Cross-Site Scripting

• Severity: medium (CVSS 4.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-10-22 · updated 2026-06-17
• Weakness: CWE-79

Description

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.
