Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Crayfish (islandora/crayfish) versions before 4.1.0 are vulnerable to remote code execution in web-accessible installations of Homarus in certain configurations. An attacker who can send requests to Homarus's /convert endpoint, which is reachable over the network, may be able to run code on the server through the Authorization header. Upgrade islandora/crayfish to 4.1.0 or later. Until then, block general Internet access to Homarus and configure Crayfish to reject requests with invalid Authorization headers before they reach the vulnerable processing step.
