      "value": "A CORS misconfiguration in Eramba Community and Enterprise Editions v3.26.0 allows an attacker-controlled Origin header to be reflected in the Access-Control-Allow-Origin response along with Access-Control-Allow-Credentials: true. This permits malicious third-party websites to perform authenticated cross-origin requests against the Eramba API, including endpoints like /system-api/login and /system-api/user/me. The response includes sensitive user session data (ID, name, email, access groups), which is accessible to the attacker\u0027s JavaScript. This flaw enables full session hijack and data exfiltration without user interaction. Eramba versions 3.23.3 and earlier were tested and appear unaffected. The vulnerability is present in default installations, requiring no custom configuration."

Esto permite que sitios web maliciosos de terceros realicen solicitudes autenticadas de origen cruzado contra la API de Eramba, incluyendo puntos finales como /system-api/login y /system-api/user/me. La respuesta incluye datos sensibles de la sesi\u00f3n del usuario (ID, nombre, correo electr\u00f3nico, grupos de acceso), que son accesibles para el JavaScript del atacante. Esta falla permite el secuestro completo de la sesi\u00f3n y la exfiltraci\u00f3n de datos sin interacci\u00f3n del usuario. Las versiones de Eramba 3.23.3 y anteriores fueron probadas y parecen no estar afectadas. La vulnerabilidad est\u00e1 presente en instalaciones predeterminadas, sin requerir configuraci\u00f3n personalizada."
