Kerentanan Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). Skor CVSS 3.1 9.9 (Critical) menurut CNA.

Deskripsi (NVD)

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.
