CVE-2023-53985Public exploitNetwork attack vector

Victim-browser script execution via unescaped p parameter

Published Jan 13, 2026 · Updated Jan 13, 2026

Reflected XSS in Zippy CRM 6.5.4 allows remote attackers to execute JavaScript in a victim's browser via a crafted URL. The p query parameter on index.php is copied unmodified into the HTML response, allowing injected tags and event handlers to run. Exploitation requires a victim to follow the attacker-controlled request; execution is confined to the CRM origin in that browser session.
