CVE-2026-92097Network attack vector

Unauthenticated shortcode execution via unfiltered URL substitution

Published Oct 14, 2026 · Updated Oct 14, 2026

Shortcode injection in HoliThemes Click to Chat 4.44 and earlier allows remote attackers to execute registered shortcodes via crafted URLs. On archive pages, greetings_dialog() substitutes REQUEST_URI into {url} after wp_kses() filtering, leaving shortcode delimiters intact for do_shortcode() in the greetings-1 and greetings-2 templates. Exposure requires an affected greeting using {url}; execution needs no authentication, and consequences depend on the shortcodes registered by WordPress, the active theme, and other plugins.
