CVE-2026-76309: The software constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. in Splunk Splunk Enterprise
CVE-2026-76309 is a medium-severity SQL injection vulnerability in Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14. It allows a low-privileged user without admin or power roles to inject SQL via the REST API due to improper neutralization of user-supplied filter values in database queries.
AI Analysis
Technical Summary
This vulnerability in Splunk Enterprise arises because the REST API incorporates externally influenced input into SQL commands without proper neutralization of special elements. As a result, low-privileged users can inject SQL commands that are evaluated by the database, potentially altering query behavior. The affected versions are those prior to 10.4.2, 10.2.6, 10.0.9, and 9.4.14. The CVSS 3.1 base score is 4.3, reflecting a medium severity with network attack vector, low privileges required, no user interaction, and limited confidentiality impact.
Potential Impact
An attacker with low privileges can perform SQL injection through the REST API, which may allow them to influence database queries. The impact is limited to confidentiality loss without integrity or availability impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch links are provided, users should monitor Splunk's advisories for updates. Until a patch is available, restrict access to the REST API to trusted users and consider applying compensating controls to limit exposure.
