CVE-2026-76335: The software constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. in Splunk Splunk Enterprise
CVE-2026-76335 is a high-severity vulnerability in Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14. It allows an authenticated user without the edit_manager_xml capability to write malicious Splunk Web Manager XML configurations. When the affected Splunk Web Manager page is opened, these configurations cause Splunk Enterprise to execute attacker-controlled operating system commands with the privileges of the Splunk Enterprise user account. This occurs because Splunk Web does not enforce the required edit_manager_xml capability before accepting XML configuration changes.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of special elements in externally influenced input used to construct code segments in Splunk Enterprise. Authenticated users lacking the edit_manager_xml capability can write malicious XML configurations that trigger execution of arbitrary OS commands when the affected Splunk Web Manager page is accessed. The flaw exists in Splunk Enterprise versions prior to 10.4.2, 10.2.6, 10.0.9, and 9.4.14 due to missing capability checks in Splunk Web. The CVSS 3.1 score is 8.8, reflecting high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with authenticated access but without the edit_manager_xml capability can execute arbitrary operating system commands as the Splunk Enterprise user. This can lead to full compromise of the affected system's Splunk Enterprise environment, including potential data exposure, modification, or service disruption.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user roles to trusted personnel only and monitor for suspicious configuration changes. Do not grant unnecessary capabilities to users. Review Splunk Web Manager XML configurations carefully before use.
