CVE-2026-4765Network attack vector

Agent-session script execution via unsanitized chat name

Published Jul 13, 2026 · Updated Jul 13, 2026

Stored XSS in RD Station Conversas Tallos Chat allows remote attackers to execute JavaScript in a support agent's browser via a crafted name. The initialization process stores the untrusted name parameter without neutralizing script-capable markup and later renders it in chat views. No account is required; execution occurs when a support agent joins the conversation, exposing that agent's application session to script actions.
