CVE-2026-76263 is a medium severity vulnerability in Splunk Enterprise that allows users without admin or power roles to delete SPL2 modules belonging to other users via the data management orchestrator interface. This occurs because the system does not verify ownership of the target resources before deletion. The issue affects Splunk Enterprise versions 10.2 and 10.4 but not versions below 10.2. There is no confirmed patch or official remediation guidance available at this time.
AI Analysis
Technical Summary
In Splunk Enterprise versions 10.2 and 10.4, a broken object-level authorization vulnerability exists in the data management orchestrator interface. Users lacking admin or power roles can delete SPL2 modules owned by other users because the system fails to verify that the requesting user owns the target resource before allowing deletion. This vulnerability does not affect versions below 10.2. The CVSS 3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, no confidentiality impact, limited integrity impact, and limited availability impact.
Potential Impact
An unauthorized user with limited privileges can delete SPL2 modules belonging to other users, potentially disrupting data processing or application functionality. There is no indication of confidentiality loss, but integrity and availability impacts are present due to unauthorized deletion of resources.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict user roles to trusted users only and monitor access to the data management orchestrator interface to limit exposure.
