DescriptionCVE.org

In versions below 2.3.8 of the AD LDAP app for Splunk SOAR, a user who holds a role with permission to run actions could cause sensitive Active Directory response data to be written to a persistent debug log file by triggering write operations through the app. For more information see Run an action in Splunk SOAR (https://help.splunk.com/en/splunk-soar/soar-on-premises/use-splunk-soar-on-premises/8.6.0/use-the-command-line-interface-to-perform-tasks-in-splunk-soar-on-premises/run-an-action-in-splunk-soar-on-premises).

AnalysisAI

Sensitive Active Directory response data exposure in the AD LDAP App for Splunk SOAR (versions below 2.3.8) allows authenticated users holding action-execution permissions to cause AD directory data to be written to a persistent debug log file. The flaw is rooted in CWE-532 (insertion of sensitive information into log files) and is reachable over the network by any low-privileged SOAR user with the appropriate role. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Authenticate to Splunk SOAR with action-execution role
Delivery
Trigger AD LDAP app query action
Exploit
App writes AD response data to debug log
Execution
Access persistent log file on host or downstream pipeline
Impact
Extract sensitive Active Directory directory data

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid Splunk SOAR account with a role that explicitly grants permission to run actions - this is a non-default, administratively assigned privilege, not available to all SOAR users. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.3 score with vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N accurately characterizes the exploitation profile: network-accessible, low complexity, requiring only a low-privileged authenticated SOAR account, with limited confidentiality impact and no integrity or availability consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Splunk SOAR user with a role granting action-execution permissions triggers an AD LDAP app action - such as a user lookup or group membership query - as part of a playbook or manual action run. The app processes the LDAP response and writes the returned AD data to a persistent debug log file. …
Remediation Upgrade the AD LDAP App for Splunk SOAR to version 2.3.8 or later, which resolves the debug log exposure per Splunk advisory SVD-2026-0806 (https://advisory.splunk.com/advisories/SVD-2026-0806). … Detailed patch versions, workarounds, and compensating controls in full report.
