CVE-2026-76314
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk49th percentile - higher than 49% of all known CVEs
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user without the "admin" or "power" roles could perform Remote Code Execution (RCE) by submitting crafted Splunk Web Manager Configuration content. The user could then access all relevant data and affect system integrity and availability. The vulnerability exists because Splunk Web evaluates manager XML expressions without sufficient input restrictions, and the associated configuration route does not require the capability expected for manager configuration changes.
Risk Assessment
The risk includes remote code execution, full data access, and compromise of system integrity and availability. The attack can be performed by a low-privileged user.
Recommendation
Upgrade Splunk Enterprise to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later. Also restrict access to manager configuration and monitor for unusual requests.

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could perform Remote Code Execution (RCE) by submitting crafted Splunk Web Manager Configuration content. The user could then access all relevant data and affect system integrity and availability. The vulnerability is possible because Splunk Web evaluates manager Extensible Markup Language expressions without sufficient input restrictions, and the associated configuration route does not require the capability expected for manager configuration changes.
