Leakage of sensitive information in logger message

Overview

• Rule ID: javascript_lang_logger

• Applicable Languages: Javascript

• Weakness ID: CWE-532

Description

Sensitive information leakage through log messages can compromise user privacy and security. This vulnerability arises when log messages include sensitive data, such as personally identifiable information (PII), making it accessible to unauthorized individuals.

Remediation Guidelines

• Avoid including sensitive data in log messages. This can result in unintended exposure of private information.

  logger.info(`User is: ${user.email}`); // unsafe
  
  

• Use non-sensitive, unique identifiers to reference users in log messages. This approach maintains user privacy while still allowing for effective logging.

  logger.info(`User is: ${user.uuid}`)
