Additionally, security teams and vulnerability management teams should review the affected scope and severity to determine the necessary

Why it matters

CVE-2026-111635 is a path traversal vulnerability in Helical Insight through 7.0.0 that allows authenticated viewers to read files outside the solution directory via the path parameter of /getExternalResource. Helical Insight administrators and users who have access to the /getExternalResource endpoint should assess their exposure and prioritize remediation.

• Read access to files outside the solution directory.
• Potential data exposure through file reading.
• Need to verify access controls for the /getExternalResource endpoint.
• Remediation priority for Helical Insight deployments.

Technical summary

The path traversal vulnerability in Helical Insight through 7.0.0 allows authenticated viewers to read files outside the solution directory via the path parameter of /getExternalResource. This vulnerability can lead to unauthorized access to sensitive files and potential data exposure. The vulnerability is caused by inadequate input validation and sanitization of the path parameter, allowing attackers to supply parent-directory segments to read any readable file with an allowed extension such as js, json, or html, bypassing per-resource access control.

Defensive priority

Assess exposure and prioritize remediation for Helical Insight deployments.

Recommended defensive actions

• Assess Helical Insight deployments for exposure to the /getExternalResource endpoint.
• Verify that access controls are in place for the affected endpoint.
• Restrict access to the /getExternalResource endpoint to only necessary users and systems.
• Monitor for suspicious activity related to the /getExternalResource endpoint.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
