If you cannot patch yet, restrict Subscriber role capabilities if possible and monitor for suspicious activity related to SQL injection attempts.

The Library Management System WordPress plugin before 3.6.7 does not sanitize and escape a user-supplied parameter before using it in a SQL statement, allowing users with a role as low as Subscriber to perform SQL injection and extract arbitrary data from the database, including user password hashes.
