CVE-2026-76343: 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

In affected versions of Splunk Enterprise, the Data Orchestration component constructs SQL commands using input from users who lack admin or power roles. Due to improper neutralization of special SQL elements and absence of parameterized queries, an attacker can inject and execute arbitrary SQL queries through the jobs endpoint. This vulnerability exposes substantial data, including jobs owned by other users and stored connection credentials. The issue is fixed in versions 10.4.2, 10.2.6, 10.0.9, and 9.4.14.

An attacker with limited privileges (non-admin, non-power roles) can execute arbitrary SQL queries, gaining unauthorized read access to most data managed by Data Orchestration. This includes sensitive information such as jobs owned by other users and stored connection credentials. The vulnerability does not impact integrity or availability according to the CVSS vector but has high confidentiality impact.

Upgrade to Splunk Enterprise versions 10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is indicated in the available data.
