Splunk On-Call API Key Disclosure (pre-1.0.43)
CVE-2026-76405 Published on August 19, 2026
Information Disclosure through Cleartext Storage in the App Key Value Store in the Splunk On-Call (VictorOps) app
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.
Weakness Type
Cleartext Storage of Sensitive Information
The application stores sensitive information in cleartext within a resource that might be accessible to another control sphere. Because the information is stored in cleartext, attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information.
