Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Crayfish, the Islandora package, in versions up to and including 4.0.0 is vulnerable to remote code execution through the hypercube component's handling of a request header. The source does not say which attacker privileges are needed beyond the ability to send requests to Hypercube's endpoints. No fixed version is listed; the source says no patch is available yet. Restrict internet access to Hypercube, since installations behind a firewall are less exposed.
