Top 10 OWASP Security Risks for Web Application & web site
Introduction
If you use a website, mobile app, or an online system, you know from experience how important its security is. Nowadays, cyber attacks have become a major problem. This issue has escalated to the point where money disappears from the banks and treasuries of various countries. Today, hundreds of thousands of websites are hacked daily. The main reason for this is the security vulnerabilities caused by web developers.
OWASP is a globally trusted source for web security. The "OWASP Top 10," which they regularly update, refers to 10 major security risks in web applications. By 2026, these risks have become more advanced, and new threats have been added due to AI, API, and cloud systems.
In this article, we will discuss the Top 10 OWASP risks with you. Whether you are a developer, or a business owner or not, I think it is mandatory to know these things because, do you know, if your data is not secure, your entire system falls into a huge danger.
"Alright, let's now see what these OWASP risks are."
1. Broken Access Control

refers to a situation where users of a website access data they shouldn't be able to access, and the potential for such access in the future. Imagine this, a normal user was able to log into the admin panel. Then it becomes a huge security disaster.
A major issue here is that web developers do not put proper permission checks, and even in 2026 systems, this risk has increased due to API-based access control mistakes.
"According to OWASP reports, a main reason for web breaches is access control failures.
2. Cryptographic Failures

To say this simply, it is the incorrect use or non-use of data encryption. If you store sensitive data like your password or credit card details without encrypting them, hackers can easily get them.
By 2026, due to cloud storage and AI systems, data flow has increased, bringing encryption mistakes to a much riskier level. If a database leak happens without proper encryption, the data of millions of users can leak in a few minutes. There is a risk. Therefore, be a bit careful when entering your personal data into a computer or a phone.
3. Injection Attacks

The meaning of injection attacks is hackers injecting malicious code into input fields. The most popular example is SQL injection.
To explain further, it is possible to hack the database by entering a code into the password field of a login form on a website or app. By 2026, advanced forms like NoSQL and GraphQL have also increased.
" One of the oldest but still most dangerous attacks categories is injection attacks"
4. Insecure Design
This cannot be called a technical flaw. This is a system design level problem. The issue that arises here is not thinking about security at the very time of designing the app. If there is a design that can bypass 2FA, no matter how good the coding is, the system is not secure.
If your design is not good, the chances of it being hacked in the future are very high.
5. Security Misconfiguration
Incorrectly configuring servers, cloud services, and APIs falls into this category. Using default passwords also belongs to this.
By 2026, as cloud systems have increased, misconfiguration errors have become an even more common thing.
Many hacks occur purely due to "publicly exposed databases and configurations."
6. Vulnerable and Outdated Components
Using old libraries, frameworks, and plugins is a huge risk. Software components that developers do not update are exploited by hackers. Imagine this, just by not updating a WordPress plugin, the whole website can be hacked.
By 2026, open source dependency attacks have already become a major threat.
7. Identification and Authentication Failures
If login systems become weak, hackers easily get the opportunity to enter your system. Weak passwords, no MFA (Multi-Factor Authentication), and session hijacking belong to this. When setting a password, you need to use a mix of letters, numbers, and symbols. Otherwise, if you put it as 123556, your system is in danger.
"Although biometric authentication is used more in 2026 systems, the risks are higher due to poor implementation."
8. Software and Data Integrity Failures
The main issue in this category is the compromise of software updates, CI/CD pipelines, and data integrity systems. Because of this, hackers can insert fake updates and install malware.
Supply chain attacks like the SolarWinds incident showed how dangerous this category is.
By 2026, due to AI-generated code pipelines, integrity checking has become even more important.
9. Security Logging and Monitoring Failures
If the logs of a system are not properly maintained, it becomes impossible to detect when an attack happens. A system without logging is exactly like a shop without a door.
"Hackers often remain in systems for months without being detected due to poor logging."
10. API Security & SSRF Attacks (Modern Threats)
By 2026, APIs are the backbone of web systems. But if API security becomes weak, massive data leaks happen.
In SSRF (Server-Side Request Forgery) attacks, the attacker uses the server to access internal systems.
Because 70%+ of modern apps are API-based, this category is one of the most critical threats.
Due to LLM (AI) integrations, new risks like “prompt injection attacks” have also been added to this group.
OWASP is like a survival guide in the modern cybersecurity world. By 2026, because web applications have become more complex, threats have become even more advanced.
If you are a developer, being aware of these risks and following secure coding practices is mandatory. If you are a business owner, you cannot ignore security investments.

FAQ
1. What is the OWASP Top 10?
The OWASP Top 10 is a globally accepted guideline that lists 10 major security risks affecting web applications. It is a reference that helps developers build secure systems.
2. Have OWASP risks changed by 2026?
Yes. Although the basic categories remain the same, new threats like API security, cloud misconfigurations, and AI-related attacks have increased. Therefore, modern updates are important.
3. Do OWASP risks apply to small websites too?
Absolutely yes. Hackers target even small websites. Security does not depend on the size.
4. What is the easiest way to avoid OWASP risks?
Secure coding, regular updates, using encryption, strong authentication, and proper logging are the basic protections.
5. Do OWASP risks affect AI systems?
Yes. New vulnerabilities like prompt injection, data leakage, and API misuse exist in AI apps. Therefore, AI security is also important.
6. Does a developer need to learn OWASP?
100% yes. OWASP knowledge is essential for every field, including web development, backend, frontend, and DevOps.
7. Is the OWASP Top 10 regularly updated?
Yes. The OWASP community does continuous research. Updates based on new threats are released, usually with a gap of a few years.
