CVE-2026-76310
CRITICALUnauthenticated users with embedded report tokens in Splunk Enterprise can download dispatch archives, recover session material, and perform administrative actions.
This vulnerability allows unauthenticated attackers to access all data available to report owners and execute administrative actions if the owner holds the 'admin' role. DIB organizations must ensure Splunk Enterprise is patched to versions 10.4.2, 10.2.6, 10.0.9, or 9.4.14 and above to prevent data exfiltration and system integrity compromise. The failure stems from REST API dispatch archive download requests not being blocked for embedded report access.
Shame score — A critical vulnerability allowing unauthenticated administrative actions and data access in a widely deployed security analytics platform, indicating a severe gap in access control and patch management.
▸ RECOMMENDED ACTION Remote code execution — patch the affected products on priority.
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who has an embedded report token could download the associated search job dispatch archive, recover session material, and use it to access all relevant data available to the report owner and affect system integrity, including by performing administrative actions when the owner holds the "admin" Splunk role. The vulnerability is possible because embedded report access does not block Representational State Transfer (REST) API dispatch archive download requests.
