CVE-2023-4507Network attack vector

Reflected XSS via unescaped q parameter

Published Aug 17, 2024 · Updated Apr 8, 2026

Reflected XSS in Zvijerka Admission AppManager 1.0.0 and earlier allows remote attackers to execute scripts through the q parameter. The plugin's administrative PHP code returns the q request value in generated HTML without sufficient input sanitization or output escaping. No authentication is required, but a user must follow a crafted link before the injected script runs in that user's browser.
