CVE-2026-71268 (GCVE-0-2026-71268)

Title
OpenPLC Runtime v3 Path Traversal in Structured Text FILE Directive Leading to Arbitrary File Write
Summary
OpenPLC Runtime v3's compile_program function (webserver/openplc.py) parses directives from uploaded Structured Text (.st) program files and writes the referenced content to with no validation that file_path stays within the ./core directory. A path-validation function, validate_file_path, exists elsewhere in the codebase (webserver/credentials.py) but is never invoked from compile_program, leaving the sink unprotected.
