CVE-2026-93339 Details
Description
Metaphor Creations Ditty (ditty-news-ticker) before 3.1.70 contains a stored cross-site scripting vulnerability that allows authenticated users with Author-level privileges or higher to inject arbitrary HTML elements by supplying malicious wrapper attribute values in layout tags. The ditty_layout_render_tag_wrapper() function inserts caller-supplied wrapper attribute values directly as HTML element names without allowlist validation, bypassing wp_kses_post() sanitization because KSES runs at save time before layout tag attributes are resolved at render time, causing the payload to execute in the browser of any visitor viewing posts or pages embedding the affected Ditty item.
A stored cross-site scripting vulnerability has been identified in Metaphor Creations Ditty (ditty-news-ticker) versions prior to 3.1.70. This vulnerability allows authenticated users with Author-level privileges or higher to inject arbitrary HTML elements. The issue arises from the ditty_layout_render_tag_wrapper() function, which directly inserts user-supplied wrapper attribute values as HTML element names without proper validation. This bypasses the wp_kses_post() sanitization, as KSES operates at save time before the layout tag attributes are fully resolved, leading to the execution of malicious payloads in the browsers of visitors viewing the affected posts or pages.
Users are advised to update to Ditty version 3.1.70 or later, where this vulnerability has been addressed.
