Allow HTML in Category Descriptions <= 1.2.4 - Authenticated (Administrator+) Stored Cross-Site Scripting via Category Descriptions

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2026-0693
CVSS Medium (4.4)
Publicly Published February 13, 2026

Researcher ZAST.AI
Description

The Allow HTML in Category Descriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via category descriptions in all versions up to, and including, 1.2.4. This is due to the plugin unconditionally removing the `wp_kses_data` output filter for term_description, link_description, link_notes, and user_description fields without checking user capabilities. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in category descriptions that will execute whenever a user accesses a page where the category description is displayed. This only affects multi-site installations and installations where unfiltered_html has been disabled.
