## What is CVE-2026-76405?

CVE-2026-76405 is a medium-severity vulnerability in Splunk On-Call (VictorOps), published on 19 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.
