      "value": "A Cross-site Scripting (XSS) vulnerability was identified in the `from_dict` method of the `AppLollmsMessage` class in parisneo/lollms prior to version 2.2.0. The vulnerability arises from the lack of sanitization or HTML encoding of the `content` field when deserializing user-provided data. This allows an attacker to inject malicious HTML or JavaScript payloads, which can be executed in the context of another user's browser. Exploitation of this vulnerability can lead to account takeover, session hijacking, or wormable attacks."

      "value": "Una vulnerabilidad de Cross-site Scripting (XSS) fue identificada en el método ’from_dict’ de la clase ’AppLollmsMessage’ en parisneo/lollms anterior a la versión 2.2.0. La vulnerabilidad surge de la falta de saneamiento o codificación HTML del campo ’content’ al deserializar datos proporcionados por el usuario. Esto permite a un atacante inyectar cargas útiles HTML o JavaScript maliciosas, que pueden ser ejecutadas en el contexto del navegador de otro usuario. La explotación de esta vulnerabilidad puede llevar a la toma de control de cuentas, secuestro de sesión o ataques tipo gusano."
