CVE-2026-76366: The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. in Splunk Splunk SOAR
CVE-2026-76366 is a medium severity vulnerability in Splunk SOAR versions equal to 8.6.0. It allows a user with a valid account to exploit REST API filtering on playbook runs to recover session tokens. These tokens can expose sensitive information accessible to the affected user. The issue arises because the REST API filters can match values that are normally hidden in responses.
AI Analysis
Technical Summary
In Splunk SOAR version 8.6.0, a vulnerability exists where REST API filtering on playbook runs can be abused by authenticated users to retrieve session tokens. This occurs because the API does not block filters from matching on values that responses otherwise conceal, leading to unauthorized exposure of sensitive session tokens. This flaw enables an attacker with valid credentials to access sensitive data tied to the affected user's permissions.
Potential Impact
An authenticated user can obtain session tokens through the REST API filtering mechanism, potentially exposing sensitive information available to that user. The vulnerability does not allow privilege escalation or denial of service but compromises confidentiality of session tokens and related data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time.
