CVE-2026-76335
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk26th percentile - higher than 26% of all known CVEs
Summary
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an authenticated user without edit_manager_xml capability could write a malicious Splunk Web Manager XML configuration. When the user opens the page, Splunk runs attacker-controlled OS commands.
Risk Assessment
The risk includes arbitrary OS command execution under the Splunk account, potentially leading to full system compromise.
Recommendation
Upgrade to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later and enforce least privilege.
Original NVD description (English source)
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an authenticated user who does not hold a role with the edit_manager_xml capability could write a malicious Splunk Web Manager Extensible Markup Language (XML) configuration. When the same user opens the affected Splunk Web Manager page, Splunk Enterprise runs attacker-controlled operating-system commands as the user account running Splunk Enterprise. The vulnerability is possible because Splunk Web does not require the edit_manager_xml capability before accepting Splunk Web Manager XML configuration changes.
