QFinch assessment
ArcadeDB from 26.2.1 before 26.10.1 contains a missing authorization vulnerability in the Bolt protocol handler that lets authenticated users read other databases' schema metadata. Attackers with credentials for one database can set the db field in RUN or BEGIN messages and call db.labels() or SHOW INDEXES to enumerate unauthorized schemas.
