The Top 10 OWASP Vulnerabilities in 2023
22 Jul 2023

In the ever-evolving landscape of cybersecurity, staying up-to-date with the latest vulnerabilities is crucial for protecting sensitive information and safeguarding digital assets. As 2023 unfolds, a new wave of threats has emerged, and it's essential for businesses and developers to remain vigilant against these potential dangers. 

Here are the top 10 OWASP vulnerabilities that have been making waves in the cybersecurity world this year up until now:

  1. Insecure APIs

Application Programming Interfaces (APIs) have become the backbone of modern software development, but their security remains a pressing concern. In 2023, the rise of API-based attacks has brought to light the importance of proper authentication, authorization, and data validation mechanisms. Failing to secure APIs can lead to unauthorized access, data breaches, and even complete system compromise.

  1. AI and ML-Based Attacks

As artificial intelligence and machine learning technologies continue to advance, so do the methods employed by cybercriminals. In 2023, we witnessed an increase in AI and ML-based attacks, which exploit vulnerabilities in poorly implemented algorithms. Adversaries are using AI to craft sophisticated attacks, identify weaknesses in systems, and evade traditional security measures.

  1. Supply Chain Attacks

The prevalence of supply chain attacks has intensified in 2023, targeting both software and hardware components. Malicious actors are compromising vendors and service providers to inject malicious code or hardware implants into legitimate products. These attacks pose significant risks to businesses and users, as they can lead to widespread compromise with minimal effort.

  1. Serverless Security Gaps

Serverless computing has gained immense popularity for its scalability and cost-efficiency. However, 2023 has seen a rise in serverless security gaps due to misconfigurations and inadequate access controls. The lack of visibility into the underlying infrastructure can leave serverless applications vulnerable to data leaks and unauthorized access.

  1. IoT Device Vulnerabilities

The ever-expanding Internet of Things (IoT) ecosystem has brought convenience and automation to our daily lives. Nevertheless, in 2023, IoT device vulnerabilities remain a major concern. Weak default credentials, lack of firmware updates, and insecure communication protocols make IoT devices enticing targets for cybercriminals.

  1. Web Application Security

Web applications continue to be an attractive target for attackers, and in 2023, new techniques have emerged to exploit their vulnerabilities. From Cross-Site Scripting (XSS) to SQL Injection, inadequate input validation and insecure coding practices are responsible for leaving web applications exposed to compromise.

  1. Mobile Application Flaws

Mobile apps have revolutionized the way we interact with technology, but their security issues persist. In 2023, mobile application flaws like insecure data storage, insufficient encryption, and weak authentication methods have been exploited by attackers, leading to privacy breaches and data theft.

  1. Ransomware Reinvented

Ransomware has evolved significantly in 2023, adapting to new trends and technologies. Sophisticated variants now utilize AI-driven targeting, multi-platform capabilities, and decentralized infrastructure, making them more challenging to detect and mitigate.

  1. Blockchain Vulnerabilities

Blockchain technology promised enhanced security, but 2023 has revealed new vulnerabilities in decentralized systems. Smart contract flaws, consensus algorithm attacks, and supply chain-related weaknesses have all contributed to the growing list of blockchain-related threats.

  1. Biometric Authentication Risks

Biometric authentication has gained popularity as a secure method to verify user identities. However, 2023 has seen an increase in biometric authentication risks, including spoofing, deepfake attacks, and compromised databases containing biometric data.


As the cybersecurity landscape continues to evolve, staying ahead of the latest OWASP vulnerabilities is crucial for individuals and organizations alike. In 2023, the emergence of sophisticated threats across APIs, AI, supply chains, and beyond requires a comprehensive and proactive approach to security. By remaining vigilant and adopting robust security practices, we can better protect ourselves and our digital assets from the ever-evolving threat landscape.
