Query-execution paths that reach record data through LSM index files or the TimeSeries engine never invoke that permission check, so an authenticated user who is denied readRecord\/deleteRecord on a type can still, with a single ordinary SQL statement, read the type&#8217;s indexed key values and record IDs (e.g. SELECT key, rid FROM INDEX:Type[field]), read MAX\/MIN values via the index shortcut, read and count TimeSeries samples, learn the type&#8217;s record count, and delete index entries (DELETE FROM INDEX:Type[field]), which desynchronizes the index from the data and can defeat unique constraints. Index and type names needed for exploitation are discoverable because SELECT FROM schema:indexes is unfiltered.
