Invoker does not have privilege to view the definer

Production Risk

Medium — view is inaccessible to the affected user.

What this means

A user is attempting to use a view whose DEFINER is a different user, but the invoking user does not have the SUPER or SET_USER_ID privilege required to invoke routines on behalf of another user.

Why it happens
  1. 1INVOKER security-context view where the current user lacks the required privileges to impersonate the definer.
  2. 2The definer account no longer exists.
How to reproduce
trigger — this will error
trigger — this will error
SELECT * FROM view_owned_by_other_user; -- current user lacks SUPER

expected output

ERROR 1947 (HY000): Invoker does not have privilege to view the definer.

Fix 1

Grant the SUPER or SET_USER_ID privilege to the invoking user

Grant the SUPER or SET_USER_ID privilege to the invoking user
GRANT SET_USER_ID ON *.* TO 'invoker'@'%';

Why this works

Allows the user to invoke routines defined by other users.

Fix 2

Recreate the view with the current user as the DEFINER

Recreate the view with the current user as the DEFINER
CREATE OR REPLACE DEFINER='invoker'@'%' VIEW v AS SELECT ...;

Why this works

Aligns the DEFINER with the user who needs to invoke the view.
