## How to fix

## Technical details

The vulnerability is an incorrect authorization check in htdocs/core/ajax/updateextrafield.php that relies on read permission instead of write permission to update extrafield values. An authenticated user with read-only access can POST objectType, objectId, field, and value parameters to persistently modify extrafield data across multiple object types. This is an authorization bypass allowing privilege escalation within the application.
