Open OnDemand Community:

Open OnDemand does not utilize Java and thus is not vulnerable to any log4j exploit. While we are not aware of any vulnerabilities in underlying system tools (e.g. SLURM, Imod) or applications commonly utilized with Open OnDemand (e.g. MATLAB, Paraview), we strongly recommend that all sites thoroughly evaluate any system tools and applications in use.
