Description

Helical Insight through 7.0.0 contains a path traversal vulnerability that allows authenticated viewers to read files outside the solution directory via the path parameter of /getExternalResource. Attackers can supply parent-directory segments to read any readable file with an allowed extension such as js, json, or html, bypassing per-resource access control.
