CVE-2026-76369: The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. in Splunk Splunk SOAR
CVE-2026-76369 is a low-severity vulnerability in Splunk SOAR versions below 8.6.0 that allows a user with the OnPrem Broker role to write files outside the intended Automation Broker log directory. This occurs because the software does not properly sanitize crafted filename inputs before writing log files, potentially enabling path traversal outside the restricted directory.
AI Analysis
Technical Summary
In Splunk SOAR versions prior to 8.6.0, the Automation Broker component accepts crafted filename inputs for log uploads without properly neutralizing special pathname elements. This allows a user holding the OnPrem Broker role to write files outside the designated Automation Broker log directory, potentially leading to unauthorized file writes. The vulnerability arises from insufficient input validation on file paths used during log file creation.
Potential Impact
The vulnerability allows users with the OnPrem Broker role to write files outside the intended log directory, which could lead to unauthorized file manipulation or overwriting files in unintended locations. However, the CVSS score of 2.7 and the description indicate that there is no confidentiality or availability impact, only limited integrity impact. There is no indication of remote exploitation without privileges or user interaction.
Mitigation Recommendations
No official patch or remediation level is provided in the vendor advisory data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict the OnPrem Broker role to trusted users only and monitor file system changes related to Automation Broker logs. Follow Splunk's documentation on managing roles and permissions to limit exposure.
