CVE-2026-76310
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who has an embedded report token could download the associated search job dispatch archive, recover session material, and use it to access all relevant data available to the report owner and affect system integrity, including by performing administrative actions when the owner holds the "admin" Splunk role. The vulnerability is possible because embedded report access does not block Representational State Transfer (REST) API dispatch archive download requests.

🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1190Exploit Public-Facing Applicationinitial access95 % - Impacto principal
T1552.007Container APIcredential access90 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation80 %
Vector CVSS N/N/N indica acceso remoto sin privilegios; descarga no autorizada de archivos de sesión (T1552.007) permite recuperar credenciales y activos; acceso con rol 'admin' implica escalada de privilegios (T1068) e impersonación de cuenta (T1078.001).
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
