CVE-2023-2119Network attack vector

Browser script execution via unescaped search_term output

Published Apr 18, 2023 · Updated Apr 8, 2026

Reflected XSS in I Thirteen Web Solution Responsive Filterable Portfolio 1.0.19 and earlier allows remote attackers to inject browser scripts. The plugin reflects the search_term HTTP parameter into a generated portfolio page without sufficient sanitization or context-appropriate output escaping. A victim must follow an attacker-crafted link; the injected script then executes in that victim's browser under the WordPress site's origin.
