Descripción técnica

In Splunk Enterprise Security versions below 8.6.1, a user who holds the ess_analyst Splunk Enterprise Security role could change User and Entity Behavior Analytics (UEBA) search macros that scheduled searches run with administrator permissions, allowing for access to all relevant data and system integrity through those searches. The vulnerability is possible because the UEBA app metadata grants analyst roles write access to search macros that should be writable only by administrator roles. For more information see Users and roles for Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/install/8.4/installation/users-and-roles-for-splunk-enterprise-security) and Roles and knowledge objects in UEBA for Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/administer/8.5/user-and-entity-behavior-analytics/roles-and-knowledge-objects-in-ueba-for-splunk-enterprise-security) in the Splunk documentation.

———Kenwood DNR1007XR udhcpd Incorrect Permission Assignment Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Kenwood DNR1007XR devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the udhcpd service. The issue results from incorrect permissions set on a resource used by the service. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of root.

——0In Splunk AI Toolkit versions below 6.0.1, a user who holds the "power" Splunk role could modify app-provided scheduled searches to run arbitrary Search Processing Language (SPL) using the permissions of the search owner, which could allow access to all relevant data and affect system integrity. The vulnerability is possible because Splunk AI Toolkit gives the "power" Splunk role permission to modify scheduled searches that run using the permissions of the search owner.7h CVE-2026-763726.6 MED

——0In Nmap Scanner versions below 3.0.15, a user who holds a role that can edit, create, or run playbooks in Splunk SOAR could run the scan network action in a Safe Mode playbook while that action is listed as read-only, which could allow for command execution or other changes on a target system through Nmap Scripting Engine scripts. The vulnerability is possible because the Nmap Scanner connector action manifest classifies the scan network action as read-only even though the action accepts script parameters that can perform write operations. For more information see Manage settings for a playbook in Splunk SOAR (https://help.splunk.com/en/splunk-soar/soar-cloud/build-playbooks/manage-playbooks-and-playbook-settings/manage-settings-for-a-playbook-in-splunk-soar-cloud) in the Splunk documentation.3h CVE-2026-763712.7 BAJ

——0In FireAMP versions below 2.1.15, a user who holds a role that can edit, create, or run playbooks in Splunk SOAR could run the add listitem action in a Safe Mode playbook while that action is listed as read-only, which could allow for unauthorized changes to file lists. The vulnerability is possible because the FireAMP connector action manifest classifies the add listitem action as read-only even though the action updates file lists. For more information see Manage settings for a playbook in Splunk SOAR (https://help.splunk.com/en/splunk-soar/soar-cloud/build-playbooks/manage-playbooks-and-playbook-settings/manage-settings-for-a-playbook-in-splunk-soar-cloud) in the Splunk documentation.3h CVE-2026-762615.3 MED

——0In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, a user who does not hold the "admin" or "power" Splunk roles could read Spacebridge asymmetric private keys, which are secrets that compromise affected Spacebridge private-key material stored in the app collection, through the Splunk Secure Gateway App Key Value Store Representational State Transfer (REST) API. The vulnerability is possible on instances upgraded from older Splunk Secure Gateway deployments when the private-key migration remains incomplete, leaving key material in a collection with an insecure default access control list.6h CVE-2026-762606.5 MED

——0In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user that holds a role with the rest_properties_get capability could read encrypted stored credentials through the Representational State Transfer (REST) API. Successful exploitation can expose relevant data protected by the stored credentials. The incorrect permission assignment is possible because the properties REST endpoint requires the rest_properties_get capability instead of the list_storage_passwords capability to read stored credentials.
