CVE-2026-76256
MediumCVSS 4.3Summary
In Splunk Enterprise below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway below 3.10.9, 3.9.23, and 3.8.70, a user without 'admin' or 'power' roles can read sensitive SAML setup and instance settings information via Splunk Secure Gateway REST API endpoints. The vulnerability is due to these endpoints not enforcing authorization requirements before returning configuration information.
Risk Assessment
Exposure of SAML configuration and instance settings could aid an attacker in further attacks, such as impersonation or privilege escalation.
Recommendation
Upgrade Splunk Enterprise and Splunk Secure Gateway to patched versions. Restrict access to REST endpoints to authorized users only.
Original NVD description (English source)
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, a user who does not hold the "admin" or "power" Splunk roles could read sensitive Security Assertion Markup Language setup and instance settings information through Splunk Secure Gateway Representational State Transfer (REST) API endpoints. The vulnerability is possible because the affected Security Assertion Markup Language setup and instance settings REST API endpoints do not enforce authorization requirements before returning configuration information.
