Perhaps excessive privileges to use views

Back to Catalog
Goal Find non-SELECT privileges to use views (for others than the owner of the view). Perhaps there should be only the privilege to make queries (SELECT statements based on the views) and data modification takes place by using routines. REFERENCES and TRIGGER privileges are definitely not needed.
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability Medium (Medium number of false-positive results)
License MIT License
Fixing Suggestion Revoke the excess privileges.

Revoke the privilege.
