CVE-2026-76295: SPL Injection through the REST API in Splunk Secure Gateway
Noroxi assessment
Priority: Monitor (action score 17/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.28% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, and Splunk Secure Gateway versions below 3.10.12, 3.9.26, and 3.8.73, a user who does not hold the "admin" or "power" Splunk roles could view dashboard and report listings beyond the requested filter scope while remaining within objects that the user can access. The vulnerability is possible because Splunk Secure Gateway does not neutralize special characters in values before it creates filters for dashboard and report requests. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access) in the Splunk documentation.
