CVSS high 7.5
Splunk

Overview

Description
lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.0, using either of the two parsers in the default configuration (with resolve_entities=True) allows untrusted XML input to read local files. Setting the resolve_entities option explicitly to resolve_entities='internal' or resolve_entities=False disables the local file access. This vulnerability is fixed in 6.1.0.

  1. In Splunk MCP Server app versions below 1.2.1, a user who holds the "admin" Splunk role could execute arbitrary commands on the underlying operating system. The vulnerability is possible because of missing input validation in the app's credential management component, which deserializes stored data without checking whether the content is of the expected type.•CVE-2026-76404
  2. In Splunk On-Call (VictorOps) app versions below 1.0.43 on Splunkbase, a user who does not hold the "admin" or "power" Splunk roles could read a partially masked Application Programming Interface (API) key from the App Key Value Store (KV Store). The exposure is possible because the Splunk On-Call (VictorOps) app does not fully mask the API key before storing it in a KV Store collection that the user can read. For more information see About the app key value store (https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/9.2/administer-the-app-key-value-store/about-the-app-key-value-store) in the Splunk documentation.•CVE-2026-76405
  3. 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.•CVE-2026-76388
  4. In Splunk Enterprise Security versions below 8.6.1, a user who holds a Splunk Enterprise Security role that contains the mc_investigation_read capability could inject Search Processing Language (SPL) through Analyst Queue search filters, allowing for access to all relevant data and system integrity available to the scheduled searches that run for that user. The vulnerability is possible because the Analyst Queue search filter handling does not validate filter field names before the fields are included in SPL searches. 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), Manage analyst workflows using the analyst queue in Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/administer/8.4/mission-control/manage-analyst-workflows-using-the-analyst-queue-in-splunk-enterprise-security), and Overview of Mission Control in Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/user-guide/8.5/mission-control/overview-of-mission-control-in-splunk-enterprise-security) in the Splunk documentation.•CVE-2026-76387
  5. In Splunk SOAR versions below 8.6.0, an unauthenticated user could spoof the source IP address in a crafted request to an Automation Broker notification endpoint and execute arbitrary code on the Splunk SOAR host. The vulnerability is possible because the Splunk SOAR Automation Broker trusts a client-supplied source IP address header as proof that the request originates from the local system. Successful exploitation can expose all relevant data, affect system integrity, and disrupt service availability. For more information see About Splunk SOAR Automation Broker (https://help.splunk.com/en/splunk-soar/splunk-automation-broker/about-splunk-soar-automation-broker/about-splunk-soar-automation-broker) in the Splunk documentation.•CVE-2026-76356
