APIs play a crucial role in facilitating communication and data exchange between software applications [2]. However, they also pose significant cybersecurity risks [2]. This article explores the vulnerabilities associated with APIs and the importance of implementing proper security measures.


The Open Web Application Security Project (OWASP) identifies broken object-level authorization (BOLA) as a top vulnerability in APIs [2]. Attackers can manipulate object IDs and gain unauthorized access to or delete user data. Cyberattacks targeting APIs have increased by 137% [2], with healthcare and manufacturing sectors being prime targets [2]. Security concerns include zombie APIs [2], DDoS attacks [1] [2] [3], authentication bypass [2], data leakage [1] [2], data exfiltration [2], and shadow APIs [2] [4]. The proliferation of APIs across industries has driven connectivity [2], operational efficiency [2], and innovation [2], but it has also brought risks. Major security breaches [1] [4], such as the Cambridge Analytica breach [4], have been attributed to API vulnerabilities [4]. Organizations use APIs to achieve interoperability [2], accelerate development [2], and enhance user experiences [2]. However, failing to secure APIs appropriately can lead to various risks, including broken object-level and user- and function-level authorization [4], excessive data exposure [3] [4], lack of resources [3] [4], security misconfiguration [4] [5], and insufficient logging and monitoring [4]. It is crucial for organizations to take API security seriously and implement best practices based on how APIs are being used [4].


API cybersecurity risks are a growing concern in today’s digital world [3]. The use of APIs has increased exponentially [3], making them vulnerable to attacks [3]. Data breaches resulting from API vulnerabilities can lead to fines [3], litigation [1] [3], and damage to a company’s reputation [3]. To protect against these threats [3], it is important to address the OWASP Top 10 vulnerabilities and implement measures such as static application security testing (SAST) and API management. By understanding and addressing these risks [3], organizations can enhance their API security and protect against potential cyberattacks [3].
