In the module "Channable" (channable) up to version 3.2.1 from Channable for PrestaShop, a guest can perform SQL injection via `ChannableFeedModuleFrontController::postProcess()`.
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.
