    CVE-2026-22208 (GCVE-0-2026-22208)

    Vulnerability from cvelistv5 – Published: 2026-02-17 14:29 – Updated: 2026-05-26 11:51

    Title
    OpenS100 Portrayal Engine Unrestricted Lua Standard Library Access
    Summary
    OpenS100 (the reference implementation S-100 viewer) prior to commit 753cf29 contains a remote code execution vulnerability via an unrestricted Lua interpreter. The Portrayal Engine initializes Lua using luaL_openlibs() without sandboxing or capability restrictions, exposing standard libraries such as 'os' and 'io' to untrusted portrayal catalogues. An attacker can provide a malicious S-100 portrayal catalogue containing Lua scripts that execute arbitrary commands with the privileges of the OpenS100 process when a user imports the catalogue and loads a chart.
