Crayfish is a collection of Islandora 8 microservices, one of which, Homarus, provides FFmpeg as a microservice. Prior to Crayfish version 4.1.0, remote code execution may be possible in web-accessible installations of Homarus in certain configurations. The issue has been patched in `islandora/crayfish:4.1.0`.

Alternatively or additionally, configure a
