Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The arcadedb-engine Maven package, versions before 26.6.1, lets an authenticated user lacking the UPDATE_SCHEMA permission, including a read-only API token, change a database's schema through SQL statements such as DROP PROPERTY, ALTER TYPE and ALTER PROPERTY. This does not expose or write record data, but it can corrupt the meaning of stored records. Upgrade to 26.6.1, which adds the missing permission checks. Until then, grant write access only to trusted users and API tokens.
