No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines, and watch the vendor's advisory for the fix.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.

Data Freshness Timeline

(refreshed 15× in last 7d / 73× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 98 of 140 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 2 repeat rows among the latest 100 are merged into the row they repeat. The 42 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
