CVE-2025-12078Network attack vector

Script execution via unsanitized postMessage data

Published Nov 18, 2025 · Updated Nov 18, 2025

Reflected XSS in ArtiBot Free Chat Bot for WebSites 1.1.7 and earlier allows remote attackers to execute scripts via postMessage data. Its postMessage path accepts attacker-controlled data and places it into a page without sufficient input sanitization or output escaping. Exploitation requires no account but requires a user to follow a crafted link, after which the script runs in that user's browser context.
