      "value": "SysReptor is a fully customizable pentest reporting platform. From version 2026.4 to before version 2026.27, the endpoints for reading and creating sharing links for personal notes is not properly authorized. This allows authenticated attackers who obtain the note ID of victim users to list and create sharing links to those users' personal notes. This gives attackers read and write access to notes of other users. This exploit works in both SysReptor Professional and Community. In Community it has, however, no impact because all users have superuser permissions and can list personal notes of other users at /admin/pentests/usernotebookpage/. This issue has been patched in version 2026.27."

Desde la versión 2026.4 hasta antes de la versión 2026.27, los endpoints para leer y crear enlaces compartidos para notas personales no están debidamente autorizados. Esto permite a atacantes autenticados que obtienen el ID de nota de usuarios víctimas listar y crear enlaces compartidos a las notas personales de esos usuarios. Esto otorga a los atacantes acceso de lectura y escritura a las notas de otros usuarios. Este exploit funciona tanto en SysReptor Professional como en Community. En Community, sin embargo, no tiene impacto porque todos los usuarios tienen permisos de superusuario y pueden listar las notas personales de otros usuarios en /admin/pentests/usernotebookpage/. Este problema ha sido parcheado en la versión 2026.27."
