SQLAlchemyDA is a generic database adapter for ZSQL methods. A vulnerability found in versions prior to 2.2 allows unauthenticated execution of arbitrary SQL statements on the database to which the SQLAlchemyDA instance is connected. All users are affected. The problem has been patched in version 2.2. There is no workaround for the problem.
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.
