CVE-2023-30868Public exploitNetwork attack vector

Script execution via unescaped post_type input

Published May 18, 2023 · Updated Apr 28, 2026

Reflected XSS in Jon Christopher CMS Tree Page View 1.6.7 and earlier allows remote attackers to inject scripts via post_type. The plugin reflects the post_type request parameter into an administrative page without sufficient input sanitization or output escaping. Exploitation requires an unauthenticated attacker to induce a user to open a crafted link, after which the script runs in that user's browser context.
