Money Manager EX WebApp (web-money-manager-ex) 1.2.2 is vulnerable to SQL Injection in the `transaction_delete_group` function. The vulnerability is due to improper sanitization of user input in the `TrDeleteArr` parameter, which is directly incorporated into an SQL query.
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.
