  3. CVE-2026-27742
Bludit version 3.16.2 contains a stored cross-site scripting (XSS) vulnerability in the post content functionality. The application performs client-side sanitation of content input but does not enforce equivalent sanitation on the server side. An authenticated user can inject arbitrary JavaScript into the content field of a post, which is stored and later rendered to other users without proper output encoding. When viewed, the injected script executes in the context of the victim’s browser, allowing session hijacking, credential theft, content manipulation, or other actions within the user’s privileges.

Summary
  • (es) Bludit versión 3.16.2 contiene una vulnerabilidad de cross-site scripting (XSS) almacenada en la funcionalidad de contenido de publicaciones. La aplicación realiza saneamiento del lado del cliente de la entrada de contenido, pero no aplica un saneamiento equivalente en el lado del servidor. Un usuario autenticado puede inyectar JavaScript arbitrario en el campo de contenido de una publicación, que se almacena y luego se renderiza a otros usuarios sin una codificación de salida adecuada. Cuando se visualiza, el script inyectado se ejecuta en el contexto del navegador de la víctima, permitiendo el secuestro de sesión, el robo de credenciales, la manipulación de contenido u otras acciones dentro de los privilegios del usuario.
