CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Cookie Notification Plugin for WordPress < 1.0.9 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Cookie Notification Plugin for WordPress the fix is 1.0.9: builds < 1.0.9 are affected, anything from 1.0.9 onward is not.
Remediation
Update to version 1.0.9, or a newer patched version
