Description

Hardcoding database credentials directly in your source code is a security risk as anyone with access to your source code and see your credentials. It’s strongly recommended to use a different approach that limits the exposure of your credentials.

Non-Compliant Code Examples

import psycopg2

conn = psycopg2.connect(database="db_name",
                        host="db_host",
                        user="db_user",
                        password="db_pass", # hardcoded password
                        port="db_port")

import mysql.connector

connection = mysql.connector.connect(
  host=host,
  user=user,
  passwd=f"password", # hardcoded password
  database=database,
  charset='utf8mb4',
  use_pure=True,
  connection_timeout=5)

import mysql.connector

connection = mysql.connector.connect(
  host=host,
  user=user,
  passwd="password", # hardcoded password
  database=database,
  charset='utf8mb4',
  use_pure=True,
  connection_timeout=5)

Compliant Code Examples

import mysql.connector

connection = mysql.connector.connect(
  host=host,
  user=user,
  passwd=password,
  database=database,
  charset='utf8mb4',
  use_pure=True,
  connection_timeout=5)

import mysql.connector

connection = mysql.connector.another_function(
  host=host,
  user=user,
  passwd=f"password",
  database=database,
  charset='utf8mb4',
  use_pure=True,
  connection_timeout=5)
