Bio-Formats versions up to and including 8.3.0 are vulnerable to XML External Entity (XXE) injection in the Leica Microsystems metadata parser, which handles files such as XLEF. An attacker who can supply a crafted metadata file to the software can cause outbound network requests, read local files the process can access, or trigger a denial of service. No fixed version is listed in the source.
