CVE-2026-20259: The software does not restrict or incorrectly restricts access to a resource from an unauthorized actor. in Splunk Splunk Enterprise
In Splunk Enterprise versions below 10.2.4 and 10.0.7, and Splunk Cloud Platform versions below 10.4.2604.0, 10.3.2512.12, 10.2.2510.15, 10.1.2507.23, 10.0.2503.14, and 9.3.2411.131, a user who holds a Splunk role that contains the high-privilege capability `edit_saved_search_owner` could reassign saved search ownership to users outside their authorized scope.

AI Analysis
Technical Summary
This vulnerability affects Splunk Enterprise versions below 10.2.4 and 10.0.7, as well as specific versions of Splunk Cloud Platform below 10.4.2604.0, 10.3.2512.12, 10.2.2510.15, 10.1.2507.23, 10.0.2503.14, and 9.3.2411.131. Users with the 'edit_saved_search_owner' capability can exploit a lack of proper access control on the saved search ownership reassignment endpoint to assign saved searches to users outside their authorized scope, potentially leading to unauthorized data access. The CVSS v3.1 score is 5.5 (medium), reflecting network attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, high confidentiality impact, low integrity impact, and no availability impact. No official remediation or patch information is provided in the source data.
Potential Impact
The vulnerability allows a high-privilege user to reassign ownership of saved searches to unauthorized users, potentially exposing sensitive data or enabling unauthorized actions within Splunk Enterprise or Splunk Cloud Platform environments. Confidentiality is highly impacted, while integrity impact is low and availability is unaffected. This could lead to unauthorized data access or privilege escalation within the scope of saved searches.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict the assignment of the 'edit_saved_search_owner' capability to trusted administrators only and monitor for unusual reassignment activity. Follow vendor advisories closely for updates on patches or official mitigations.
