CVE-2026-76312
CRITICALUnauthenticated users can access all data and affect system integrity in Splunk Enterprise by reading HTML source of embedded reports due to improper authorization boundary enforcement.
CVE-2026-76312 allows unauthenticated attackers to access all relevant data and compromise system integrity in Splunk Enterprise versions below 10.4.1, 10.2.6, 10.0.9, and 9.4.14 by exploiting exposed session material in embedded report archives. DIB organizations must patch immediately to prevent data exfiltration and integrity breaches, as this flaw bypasses standard authentication controls. The failure stems from incorrect dispatch archive download path enforcement, exposing sensitive session data.
Shame score — A critical data exposure and integrity flaw in a widely deployed SIEM platform that allows unauthenticated access to all data, indicating severe authorization boundary failures.
▸ RECOMMENDED ACTION Critical severity — schedule patching of the affected products.
In Splunk Enterprise versions below 10.4.1, 10.2.6, 10.0.9, and 9.4.14, an unauthenticated user who can read the Hypertext Markup Language (HTML) source of a page that embeds a Splunk report could use exposed session material to access all relevant data and affect system integrity. The vulnerability is possible because the dispatch archive download path does not correctly enforce the embedded-report authorization boundary and includes sensitive session material in archived search-job data.
