Potential fix for https://github.com/octodemo/node-calculator-v11-sk/security/code-scanning/1
To fix the problem, we should ensure that the method name provided by the user (
req.query.operation) is only used to access own properties of theoperationsobject, and that the resulting value is a function. This can be done by replacing the current lookup and check with a combination ofObject.prototype.hasOwnProperty.call(operations, req.query.operation)andtypeof operations[req.query.operation] === 'function'. This ensures that only explicitly defined operations are allowed, and that the value is a function before calling it. The changes should be made in thecalculatefunction inapi/controller.js, specifically around lines 25–29.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
