Kirki <6.3.1 WP plugin unsanitized SVG upload risk
CVE-2026-84223 Published on September 20, 2026

Kirki 6.0.0 - 6.3.0 - Author+ Stored XSS via Unsanitized SVG Upload
The Kirki WordPress plugin before 6.3.1 does not sanitize uploaded SVG files while making them uploadable site-wide, allowing users with author-level access and above to upload a file containing JavaScript which is then served from the site's own origin and runs in the session of anyone who opens it.
