    Policy on information provided in Critical Security Alert and Security Patch Updates

    Splunk continuously monitors for vulnerabilities discovered through scans, offensive exercises, employees or externally reported by vendors or researchers. Splunk follows industry best practices to discover and remediate vulnerabilities. To report a security vulnerability, please submit to the Security Vulnerability Submission Portal.

    Splunk will not provide additional information about the specifics of vulnerabilities beyond what is provided in the Critical Security Alert or the Security Patch Update. Splunk does not distribute active exploit code (i.e. proof of concept code) for vulnerabilities in our products.


    Applicability of Critical Security Alerts and Quarterly Security Updates

    The Splunk teams regularly evaluate Critical Security Alerts, Quarterly Security Patch Updates and Third Party bulletins as they become available and apply the relevant patches in accordance with applicable change management processes.

    Customers requiring additional information that is not addressed in the Critical Patch Update Advisory may obtain information by going to the Support Portal and submitting a New Case
