A SQL injection vulnerability in Mybatis plus versions below 3.5.6 allows remote attackers to obtain database information via a Boolean blind injection. NOTE: the vendor's position is that this can only occur in a misconfigured application; the documentation discusses how to develop applications that avoid SQL injection.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
