Root Cause Analysis
The vulnerability stemmed from incomplete sanitization in script return value handling. The commit diff shows the patched version added resolveTypeAndSanitize() to recursively sanitize List/Map elements, while the original code (shown in the patch's '-' lines) only sanitized CharSequence types. This matches the CVE description about unescaped List/Map values in Reactive Reference Parameters. The eval function is the entry point for script evaluation and was the root cause of insufficient escaping.
