An attacker can achieve arbitrary client-side script execution by crafting an AI agent whose system prompt instructs the underlying Large Language Model (LLM) to embed malicious script payloads (e.g., SVG-based XSS) into its chat responses. When a user interacts with such a malicious agent or accesses a direct link to a conversation containing an XSS payload, the script executes in the user's browser. Successful exploitation can lead to the theft of sensitive information, such as JWT session tokens, potentially resulting in account hijacking."},{"lang":"es","value":"Vulnerabilidad de cross-site scripting (XSS) almacenado en Chaindesk hasta el 26/05/2025 en su componente de chat del agente. Un atacante puede ejecutar scripts arbitrarios del lado del cliente manipulando un agente de IA cuyo mensaje del sistema indica al Modelo de Lenguaje Grande (LLM) subyacente que incorpore payloads de scripts maliciosos (p. ej., XSS basado en SVG) en sus respuestas de chat.
