Code Examples
Compliant code
The server side of the application performs credential validation for each user
const changePassword = (req, res) => {
if (isValidUser(req.body.user) && isValidCredentials(req.body.userSession)) {
const newPassword = req.body.newPassword;
changeUserPassword(req.body.userId, newPassword);
}
}
Non compliant code
The server side of the application does not validate user permissions before changing passwords
const changePassword = (req, res) => {
if (isValidUser(req.body.user)) {
const newPassword = req.body.newPassword;
changeUserPassword(req.body.userId, newPassword);
}
}
