Splunk SOAR: Use of non-canonical URL paths for authorization decisions
Summary
Splunk SOAR versions below 8.7.0 contain a flaw (CWE-647) in which URL paths are used for authorization decisions without being normalized to a canonical form. An attacker with a valid low-privilege SOAR account could potentially reach functions that should be restricted, with high impact on confidentiality, integrity and availability (CVSS 8.8). The CVE is one of several SOAR vulnerabilities fixed together in advisory SVD-2026-1011, and no technical details have been published by Splunk.
Affected
- Splunk SOAR below 8.7.0
Fixed in
- Splunk SOAR 8.7.0 or higher
Workaround
- None found. Splunk only recommends the upgrade.
- Unknown whether configuration changes, such as restricting access to the SOAR web interface or API, reduce exposure.
Exploitation
- No evidence of exploitation in the wild found.
- CISA SSVC (Vulnrichment): exploitation none, automatable no.
- No public proof of concept found.
Our recommendation
- Inventory all Splunk SOAR instances and check whether any run a version below 8.7.0.
- Upgrade to Splunk SOAR 8.7.0 or higher. This single upgrade addresses all CVEs in advisory SVD-2026-1011.
- Until patched, review SOAR user accounts and limit access to the web interface and API to required users and networks.
- Monitor SOAR access logs for unusual requests to restricted paths.
