CVE-2025-51860
Stored Cross-Site Scripting (XSS) in TelegAI (telegai.com) 2025-05-26 in its chat component and character container component. An attacker can achieve arbitrary client-side script execution by crafting an AI Character with SVG XSS payloads in either description, greeting, example dialog, or system prompt(instructing the LLM to embed XSS payload in its chat response). When a user interacts with such a malicious AI Character or just browse its profile, the script executes in the user's browser. Successful exploitation can lead to the theft of sensitive information, such as session tokens, potentially resulting in account hijacking.

Un atacante puede ejecutar scripts arbitrarios del lado del cliente manipulando un personaje de IA con payloads XSS SVG en la descripción, el saludo, el diálogo de ejemplo o el mensaje del sistema (lo que indica al LLM que incorpore el payload XSS en su respuesta de chat). Cuando un usuario interactúa con dicho personaje de IA malicioso o simplemente consulta su perfil, el script se ejecuta en el navegador del usuario. Una explotación exitosa puede provocar el robo de información confidencial, como tokens de sesión, lo que podría resultar en el secuestro de cuentas."
