CVE-2026-76363 Overview
CVE-2026-76363 is a SQL injection vulnerability in Splunk SOAR versions below 8.6.0. The flaw resides in the playbook automation data APIs, which incorporate user-supplied input into database queries without proper neutralization. An authenticated user holding the Automation Engineer role can execute arbitrary Structured Query Language (SQL) statements against the Splunk SOAR database. Successful exploitation permits full create, read, update, and delete operations against stored data. The issue is tracked as [CWE-943: Improper Neutralization of Special Elements in Data Query Logic] and documented in Splunk Security Advisory SVD-2026-0804.
Critical Impact
An authenticated Automation Engineer can run arbitrary SQL against the Splunk SOAR database, enabling full manipulation of playbook, case, and automation data.
Affected Products
- Splunk SOAR versions below 8.6.0
- Splunk SOAR playbook automation data APIs
- Splunk SOAR Cloud deployments running affected versions

Technical Details for CVE-2026-76363
Vulnerability Analysis
The vulnerability affects the playbook automation data APIs in Splunk SOAR. These endpoints accept parameters from authenticated users and pass them into backend database queries without proper sanitization or parameterization. An attacker with the Automation Engineer role can inject arbitrary SQL fragments that the database executes with the privileges of the SOAR application. Because the SOAR database stores playbooks, cases, artifacts, credentials metadata, and automation state, injection provides broad access to sensitive orchestration data. Exploitation requires valid credentials and role assignment, which limits opportunistic attacks but exposes environments where the role is over-provisioned.
Root Cause
The root cause is improper neutralization of special elements used in a SQL command [CWE-943]. Splunk SOAR playbook automation data APIs concatenate or interpolate user-supplied input directly into SQL statements. The code path does not use prepared statements or bound parameters, so metacharacters retain their SQL semantics when they reach the database engine.
Attack Vector
Exploitation is network-based and requires an authenticated session for an account assigned the Automation Engineer role. The attacker submits crafted input to a vulnerable playbook automation data API endpoint. The injected SQL executes against the SOAR database with application-level privileges. No user interaction is required. Because the confidentiality and integrity impacts are high, an attacker can read arbitrary tables and modify or delete records, including playbook definitions and automation history. Refer to Splunk Security Advisory SVD-2026-0804 for vendor-confirmed technical detail.
Detection Methods for CVE-2026-76363
Indicators of Compromise
- Unexpected SQL metacharacters such as ', --, ;, or UNION in request bodies or query parameters sent to Splunk SOAR playbook automation data API endpoints.
- Unusual database activity originating from the SOAR application account, including bulk SELECT, UPDATE, or DELETE statements outside normal playbook execution windows.
- API calls from Automation Engineer accounts that deviate from established baselines in frequency, source IP, or endpoint path.
Detection Strategies
- Enable verbose API request logging on the SOAR platform and inspect payloads submitted by accounts with the Automation Engineer role.
- Correlate SOAR application logs with PostgreSQL query logs to identify statements that do not originate from parameterized queries.
- Alert on authenticated sessions performing high-volume or schema-enumeration queries against the SOAR database.
Monitoring Recommendations
- Forward SOAR audit logs and database query logs to a centralized SIEM for correlation and retention.
- Baseline normal Automation Engineer API usage and alert on statistical deviations.
- Review role assignments regularly and flag any new accounts granted the Automation Engineer role.
How to Mitigate CVE-2026-76363
Immediate Actions Required
- Upgrade Splunk SOAR to version 8.6.0 or later as directed in Splunk Security Advisory SVD-2026-0804.
- Audit all accounts assigned the Automation Engineer role and remove the role from users who do not require it.
- Rotate credentials and API tokens for any Automation Engineer accounts suspected of compromise.
Patch Information
Splunk has addressed CVE-2026-76363 in Splunk SOAR version 8.6.0. Administrators should follow the upgrade guidance in Splunk Security Advisory SVD-2026-0804. Splunk SOAR Cloud tenants should confirm their deployment has been updated to a fixed release.
Workarounds
- Restrict assignment of the Automation Engineer role to a minimal set of trusted operators until patching is complete.
- Place SOAR management interfaces behind network segmentation and require multi-factor authentication for privileged accounts.
- Monitor the playbook automation data APIs for anomalous input and block suspicious requests at an upstream reverse proxy or web application firewall.
