How to fix

Fixed in: 4.18.9, 5.11.2

Technical details

The vulnerability exists in the element search endpoint where the attribute parameter is concatenated directly into SQL queries without sanitization. Because PDO is configured with emulated prepares enabled, stacked SQL statements execute, giving unauthenticated attackers both read and write access to the application database. Attackers can set the admin flag on user accounts or overwrite password hashes to gain administrator access.

Affected products

Craft CMS 4.0.0 before 4.18.9, 5.0.0 before 5.11.2
