CVE-2025-25286 Information

Description

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. Some workarounds are available. The exploit requires making a request against the Homarus’s /convert endpoint; therefore the ability to exploit is much reduced if the microservice is not directly accessible from the Internet so: Prevent general access from the Internet from hitting Homarus. Alternatively or additionally configure auth in Crayfish to be more strongly required such that requests with Authorization headers that do not validate are rejected before the problematic CLI interpolation occurs.
