Root Cause Analysis

The core vulnerability stems from 3 key factors:

The Sprig template engine's default TxtFuncMap included dangerous functions (env/expandenv) that were accessible in templates
These functions were explicitly removed in the security patch (shown in treenode/template.go diff)
The /api/template/renderSprig endpoint processed user-controlled templates without initially sanitizing these functions While the path validation fixes are important, the root SSTI vulnerability was enabled by the presence of these Sprig template functions in the template processing stack.
