CVE-2026-76269 Splunk CVE debrief

Who should care

Splunk Enterprise administrators and security teams should assess exposure and prioritize remediation to prevent unauthorized data exposure. They should verify and restrict access to search job information through the REST API, monitor search job retrieval activity for suspicious behavior, and review compensating controls for exposed systems.

Why it matters

CVE-2026-76269 is a medium-severity vulnerability in Splunk Enterprise that allows users without 'admin' or 'power' roles to access search job information from other users through the REST API. This could lead to unauthorized data exposure. Splunk Enterprise administrators and security teams should assess exposure and prioritize remediation.

• Verify and restrict access to search job information through the REST API to prevent unauthorized data exposure
• Update Splunk Enterprise to version 10.4.3, 10.2.7, 10.0.10, or 9.4.15 to address the vulnerability
• Monitor search job retrieval activity for suspicious behavior to detect potential exploitation

Technical summary

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, a user without 'admin' or 'power' roles can access search job information from other users through the REST API due to improper access control. This allows access to search query text, job metadata, results, and preview results, potentially leading to unauthorized data exposure. The vulnerability is possible because the REST API does not fully validate job ownership before returning search job information. To address this, users should update Splunk Enterprise to a patched version and restrict access to search job information.

Defensive priority

Medium priority for Splunk Enterprise administrators and security teams

Recommended defensive actions

• Review and update Splunk Enterprise to version 10.4.3, 10.2.7, 10.0.10, or 9.4.15
• Restrict access to search job information through the REST API
• Monitor search job retrieval activity for suspicious behavior
• Verify and restrict access to search job information to prevent unauthorized data exposure
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
