{"id":"CVE-2026-93339","published":"2026-09-21T15:17:35.617","lastModified":"2026-09-21T16:17:27.950","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.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://wordpress.org/plugins/ditty-news-ticker/#developers","tags":[]},{"url":"https://www.vulncheck.com/advisories/ditty-stored-xss-via-layout-tag-wrapper-attribute","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw allows authenticated users with Author-level privileges or higher to inject arbitrary HTML elements by supplying malicious wrapper attribute values, leading to cross-site scripting attacks.","exploitability":"Exploitation requires an authenticated user with Author-level access and knowledge of the vulnerability; it is moderately difficult due to the need for specific input manipulation.","blast_radius":"If exploited, this could result in arbitrary HTML injection affecting any visitor viewing posts or pages embedding the affected Ditty item, potentially leading to data theft or redirection.","remediation":"Update to Ditty version 3.1.70 or higher to mitigate the vulnerability.","tags":["xss","auth-bypass","web","update"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:25:36.718Z"}}
