A SQL injection issue in the gVectors wpDiscuz plugin 5.3.5 and earlier for WordPress allows remote attackers to execute arbitrary SQL commands via the order parameter of a wpdLoadMoreComments request. (No 7.x versions are affected.)
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.
