CVE-2026-4004Network attack vector

Authenticated shortcode execution via unchecked AJAX parameters

Published Mar 21, 2026 · Updated Mar 21, 2026

Code injection in Eoxia Task Manager 3.0.2 and earlier allows remote authenticated users to execute arbitrary WordPress shortcodes. The search AJAX handler's callback_search() function passes sanitized but bracket-bearing task_id, point_id, categories_id, or term input into do_shortcode() without a capability check. Subscriber-level access is sufficient, and the resulting impact is limited to functionality exposed by shortcodes registered on the site.
