Machine-written summary

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

Versions of the com.arcadedb:arcadedb-server Maven package before 26.7.2 are affected. Any user with an account on the server who is authorized for one database can read and write other databases through about 14 HTTP endpoints for batch, time series, Prometheus and Grafana, because these endpoints skip the per-database access check. Upgrade to 26.7.2 or later. The source gives no workaround besides upgrading.
