Common API Security Problems

Understanding and Mitigating Common API Security Problems

Common API security problems include:

  • Broken Authentication: Weaknesses in the authentication mechanisms that allow attackers to compromise passwords, keys, or session tokens.

  • Excessive Data Exposure: APIs that expose more data than necessary, potentially leaking sensitive information.

  • Lack of Resources & Rate Limiting: APIs that do not implement proper rate limiting, making them vulnerable to denial-of-service (DoS) attacks.

  • Broken Function Level Authorization: Similar to BOLA, but at the function level, where attackers can access functions they shouldn't.

  • Unsafe Consumption of APIs: APIs that are not properly secured can be misused by clients, leading to various security issues.
