CVE-2026-14480

CVE-2026-14480 affects OpenPLC Runtime v3. An authenticated user can write arbitrary files via the legacy web UI program-upload workflow by storing a attacker-controlled filename (prog_file) that is later used as the destination path. Python os.path.join() honors absolute paths, enabling writes a...

OpenPLC v3

ADVISORY SUMMARY Successful exploitation of this vulnerability could allow an authenticated attacker to write arbitrary files to the filesystem and escalate this into arbitrary native code execution through the normal OpenPLC program compilation process, potentially resulting in code execution...
