The OWASP Top 10 is one of the most widely used application security references for identifying and mitigating the most critical web application security risks. This guide explains the OWASP Top 10 risks, real-world examples, remediation best practices, and how modern AppSec and software supply chain security solutions help organizations reduce risk across the SDLC.
The Open Web Application Security Project (OWASP)
The Open Web Application Security Project (OWASP) is a leading nonprofit organization dedicated to improving software security. OWASP is known for its transparency and commitment to community-driven solutions, which has made it a go-to resource for developers, security professionals, and organizations seeking to adopt best security practices. Among its many contributions, one of the most significant is the OWASP Top 10, a regularly updated list of the most critical web application security risks affecting modern applications. It highlights the most severe vulnerabilities in web applications, based on real-world data and expert insights.
OWASP’s mission is to make security accessible and understandable, providing tools, frameworks, and knowledge to help secure applications from the ground up. The OWASP Top 10 serves as a practical framework to help developers focus on the vulnerabilities that matter most, ensuring they can implement the necessary solutions effectively.
The OWASP Top 10
The OWASP Top 10 is a foundational application security resource for organizations securing modern web applications. For any organization working to secure web applications. It outlines the most critical security threats, offering insights into the common ways applications are compromised. The OWASP Top 10 vulnerabilities highlight these top risks, offering actionable recommendations to mitigate them. Addressing these vulnerabilities head-on is essential for strengthening the security of any application.
What is the OWASP Top 10 and Their Remedies?
The OWASP Top 10 is a globally recognized awareness document published by the Open Web Application Security Project (OWASP). It identifies the most critical security risks affecting modern web applications based on real-world attack data, community research, and industry analysis. The list helps developers, AppSec teams, DevSecOps engineers, and security leaders prioritize the vulnerabilities that pose the greatest risk to applications, APIs, and software supply chains.
The current OWASP Top 10 includes security categories such as Broken Access Control, Injection, Security Misconfiguration, Vulnerable and Outdated Components, Software and Data Integrity Failures, and Server-Side Request Forgery (SSRF). Understanding these risks and implementing the appropriate remediation strategies is essential for building secure applications, reducing software security exposure, and protecting organizations against modern cyber threats.

1. Broken Access Control (A01:2021)
What is Broken Access Control?
Broken Access Control occurs when users gain unauthorized access to data or actions. For example, an attacker might manipulate a URL to obtain admin access. OWASP found this issue in 94% of tested applications, making it one of the most common OWASP Top 10 security vulnerabilities.
Remedies for Broken Access Control
To mitigate this risk, enforce least privilege access, implement multi-factor authentication (MFA) for sensitive operations, and regularly audit user permissions.
Xygeni’s Secrets Security helps protect sensitive information like API keys and tokens, reducing the risk of access control violations. Continuous monitoring ensures the integrity of your system.
Rael-World Example
In 2019, First American Financial Corp exposed over 850 million sensitive records due to improper access control. Attackers could simply modify a URL to access confidential documents. By neglecting to secure the access points properly, the company left sensitive data vulnerable. This incident emphasizes the need to validate user roles and ensure that only authorized individuals can access sensitive information.
Why does it matter today? Modern applications expose APIs, cloud services, and distributed user roles, making unauthorized access one of the most common and damaging security risks affecting sensitive business data.
2. Cryptographic Failures (A02:2021)
What are Cryptographic Failures?
Cryptographic Failures occur when systems fail to properly encrypt sensitive data, allowing attackers to intercept and misuse it. Strong encryption is essential for protecting sensitive data.
Remedies for Cryptographic Failures
Encrypt stored data with AES-256 and enforce TLS 1.2 or higher for data in transit. Regularly rotate encryption keys and secure them with proper access controls.
Xygeni’s Infrastructure as Code (IaC) Security checks encryption settings during deployment to prevent weaknesses in encryption policies.
Real-World Example
In 2017, Exactis, a data aggregation firm, exposed 340 million individual records due to improper encryption. Attackers accessed personal information like names, addresses, and phone numbers because the data was stored in plaintext. This breach demonstrates the risks of failing to encrypt sensitive data. By applying proper encryption standards such as AES-256 for data at rest and TLS for data in transit, organizations can protect their data from unauthorized access.
Why does it matter today? Organizations increasingly store and transfer sensitive customer, financial, and authentication data across cloud environments, making strong encryption essential for protecting privacy and compliance.
3. Injection (A03:2021)
What are Injection Attacks?
Injection vulnerabilities, such as SQL Injection, allow attackers to insert malicious code into your system, enabling them to manipulate or steal data. Injection attacks remain one of the most common and impactful application security risks affecting modern web applications.
Remedies for Injection Attacks
Use parameterized queries and validate user inputs. Avoid dynamic queries whenever possible to minimize risks.
Xygeni’s Anomaly Detection monitors CI/CD pipelines for abnormal behavior, catching potential injection attempts in real-time.
Real-World Example
In 2017, Equifax suffered a massive data breach that exposed the personal information of 147 million customers. The breach resulted from an SQL injection vulnerability, allowing attackers to manipulate the company’s website and access sensitive data stored in the database. Organizations must ensure that their systems properly sanitize user inputs. Regular patching and securing SQL queries could have prevented this vulnerability.
Why does it matter today? Injection vulnerabilities continue to impact web applications, APIs, and AI-assisted development workflows where unvalidated input reaches interpreters, databases, or backend systems.
4. Insecure Design (A04:2021)
What is Insecure Design?
Insecure Design happens when developers fail to integrate security into the initial design phase, which creates vulnerabilities that are difficult to fix later. These weaknesses are difficult to remediate once applications reach production environments.
Remedies for Insecure Design
Incorporate secure design principles and threat modeling early in the development lifecycle. Regularly assess your design for potential weaknesses and fix them before they become critical issues.
Xygeni’s Application Security Posture Management (ASPM) identifies potential design flaws before attackers can exploit them, ensuring developers embed security into their product from the start.
Real-World Example
A more recent real-world example of Insecure Design is the Microsoft Exchange ProxyShell vulnerabilities in 2021. Attackers exploited design flaws in Microsoft Exchange’s authentication and access control mechanisms, allowing them to remotely execute code on vulnerable servers. These vulnerabilities were not implementation errors, but rather fundamental design weaknesses that made exploitation possible even after patches were applied incorrectly. This breach underscores the importance of integrating security at the design phase to prevent vulnerabilities from being built into the system.
Why does it matter today? Security weaknesses introduced during the design phase are difficult and expensive to fix later, especially in cloud-native and rapidly evolving development environments.
5. Security Misconfiguration (A05:2021)
What is Security Misconfiguration?
Security Misconfigurations occur when attackers exploit improperly configured systems, such as those using default settings or leaving unnecessary ports open. Misconfigurations remain one of the leading causes of cloud and application security incidents.
Remedies for Security Misconfiguration
Automate configuration checks using Infrastructure as Code (IaC) and conduct regular security audits. Keep all systems updated with the latest patches.
Xygeni’s IaC Security scans for misconfigurations before deployment and enforces security policies consistently across all environments.
Real-World Example
In 2018, NASA experienced a breach because misconfigured settings in Atlassian JIRA exposed sensitive project and employee data. Attackers accessed the information due to the open configuration. Automated security checks and the enforcement of proper configuration policies could have prevented this breach. Regular audits would have detected the vulnerability before the attackers exploited it.s
Why does it matter today? Misconfigured cloud services, CI/CD pipelines, containers, and exposed administrative interfaces remain one of the leading causes of modern security breaches.
6. Vulnerable and Outdated Components (A06:2021)
What are Vulnerable and Outdated Components?
Vulnerable and outdated components occur when you use third-party libraries or frameworks with known security flaws. Attackers can exploit these vulnerabilities to compromise your application. This is a particularly dangerous threat, as up to 60% of modern applications are built with third-party components.
Remedies for Vulnerable and Outdated Components
Regularly update third-party libraries and dependencies, and use Software Composition Analysis (SCA) tools to detect and patch vulnerabilities.
Xygeni’s Open Source Security scans your dependencies to prevent using outdated or malicious components, helping you maintain a secure application.
Real-World Example
In 2017, Apache Struts had an unpatched vulnerability that led to the Equifax breach, affecting millions of users. The vulnerability was in Apache Struts 2, a widely used framework, and Equifax failed to apply the patch in time. This left their systems exposed to exploitation. Timely updates and regular vulnerability scanning would have prevented this breach.
Why does it matter today? Modern applications heavily depend on open source packages and third-party libraries, making software supply chain attacks and vulnerable dependencies a growing AppSec concern.
7. Authentication Failures (A07:2021)
What are Identification and Authentication Failures?
These vulnerabilities occur when authentication mechanisms are weak or improperly implemented, allowing attackers to bypass security controls.
Remedies for Identification and Authentication Failures
Implement strong password policies, enforce multi-factor authentication (MFA), and audit authentication logs to prevent unauthorized access.
Xygeni’s Secrets Security helps secure your credentials, reducing the risk of leaks during the authentication process.
Real-World Example
In 2020, the Ring security camera breach was caused by weak passwords. Attackers used simple passwords and gained access to live video feeds from thousands of users’ cameras. This breach highlights the critical need for stronger authentication practices. Therefore, implementing multi-factor authentication (MFA) and enforcing strong password policies would have easily prevented unauthorized access.
Why does it matter today? Weak authentication mechanisms continue to enable account takeovers, credential stuffing attacks, and unauthorized access across SaaS, cloud, and enterprise applications.
8. Software and Data Integrity Failures (A08:2021)
What are Software and Data Integrity Failures?
These vulnerabilities occur when code or infrastructure doesn’t protect against tampering. Attackers can compromise build pipelines, dependencies, or deployment processes, injecting malicious code into trusted updates. This type of flaw has become a major concern due to the rise of supply chain attacks, where even trusted third-party components are targeted to infiltrate networks.
Remedies for Software and Data Integrity Failures
To mitigate this, implement code signing, use secure build processes, and verify the integrity of all third-party components.
Xygeni’s CI/CD Security ensures that your pipelines are secure and monitored for anomalies. Xygeni’s Anomaly Detection can identify suspicious activities that might indicate tampering.
Real-World Example
In 2024, a significant supply chain attack targeted XZ Utils, a widely used compression library in Linux systems. XZ Utils is a critical tool used for compressing files, trusted by thousands of organizations. However, attackers successfully compromised the project’s build process by injecting a backdoor into the code.
The attackers went unnoticed for some time, which meant systems relying on the compromised library were vulnerable to remote code execution and further exploitation. As a result, these attackers gained control over affected systems, leading to data breaches and the compromise of sensitive information.
This incident serves as a clear reminder of the dangers posed by supply chain attacks. Even a widely trusted library can be manipulated to compromise numerous systems. By ensuring secure build processes, using code-signing techniques, and continuously monitoring third-party components, organizations can prevent such vulnerabilities from infiltrating their systems.
Why does it matter today? Software supply chain attacks targeting build pipelines, package registries, dependencies, and CI/CD systems have become a major risk for modern software development.
9. Security Logging and Monitoring Failures (A09:2021)
What are Security Logging and Monitoring Failures?
These failures occur when applications don’t log security events properly or lack monitoring mechanisms. Without detailed logs, detecting and responding to attacks becomes difficult. These weaknesses often delay breach detection, allowing attackers to exploit systems over extended periods.
Remedies for Security Logging and Monitoring Failures
Enable comprehensive logging for all critical actions, store logs securely, and ensure they are monitored for suspicious activities. Furthermore, use automated tools to alert you to potential threats.
Xygeni’s Anomaly Detection helps identify unusual activities in real-time. Additionally, CI/CD Security ensures that logging and monitoring configurations are consistently applied across environments.
Real-World Example
In 2023, Uber experienced a data breach that compromised the personal information of thousands of drivers. The breach occurred when a third-party law firm, Genova Burns, experienced a security incident, exposing the data. Despite the fact that alerts were triggered, Uber’s monitoring systems failed to detect and respond to the attack promptly.
The attackers gained access to sensitive information, including names, phone numbers, and driving records. This delay was primarily due to a lack of comprehensive logging and inadequate monitoring systems.
Had Uber properly monitored access to its systems and implemented better logging practices, they could have detected the breach much sooner. As a result, the company could have minimized reputational damage and financial losses. This breach underscores the critical importance of maintaining effective logging and monitoring systems to detect and mitigate threats early.
Why does it matter today? Without proper visibility and monitoring, organizations struggle to detect attacks early, allowing attackers to remain undetected for extended periods.
10. Server-Side Request Forgery (SSRF) (A10:2021)
What is Server-Side Request Forgery?
SSRF occurs when attackers trick a server into making requests to unintended locations, often accessing internal services that should be restricted. This vulnerability allows attackers to access sensitive data or execute commands on internal systems.
Remedies for SSRF
To prevent SSRF, validate all user inputs and restrict the server’s ability to make outbound requests. Additionally, use allowlists to control which URLs the server can access.
Xygeni’s CI/CD Security helps monitor pipelines for potential SSRF vulnerabilities. Furthermore, Xygeni’s Anomaly Detection can catch unexpected or suspicious request patterns.
Real-World Example
In 2022, a significant vulnerability in Microsoft Exchange (CVE-2022-41040) was exploited by attackers using SSRF techniques. Attackers were able to send malicious requests to the Exchange server, bypassing internal security protections.
Once inside, attackers accessed internal systems and compromised sensitive data. By exploiting SSRF, they gained unauthorized access to restricted internal resources, leading to substantial security breaches.
SSRF vulnerabilities are particularly dangerous because they give attackers access to internal systems that should not be exposed to the public. Had Microsoft implemented stricter input validation and outbound request restrictions, they could have blocked the attackers’ attempts to exploit this vulnerability. This breach demonstrates the importance of controlling server requests to sensitive internal resources and ensuring that only trusted, verified sources can interact with them.
Why does it matter today? Cloud-native architectures and internal APIs have increased the impact of SSRF vulnerabilities, which attackers use to access sensitive internal services and metadata systems.
Why the OWASP Top 10 Still Matters
The OWASP Top 10 vulnerabilities are crucial for organizations aiming to secure their applications from the most common and dangerous threats. These risks are not theoretical; they represent real-world risks that can lead to data breaches, financial loss, and reputational damage. By proactively addressing these vulnerabilities, organizations can significantly reduce the risk of successful attacks and ensure that their systems are resilient against evolving threats.
Furthermore, implementing the recommended remedies in the list of OWASP Top 10 vulnerabilities helps organizations take a strategic approach to security. For example, strengthening access control, securing encryption practices, and mitigating supply chain risks all play vital roles in addressing these vulnerabilities. As a result, organizations reduce the attack surface, making it more difficult for attackers to exploit weaknesses in the system.
As cyber threats evolve, it’s essential for organizations to stay ahead of potential vulnerabilities. By taking action early, organizations ensure long-term protection for their applications and maintain the trust of their users.
Beyond the traditional OWASP Top 10 vulnerabilities, organizations increasingly face malicious open source packages, dependency confusion attacks, typosquatting campaigns, insecure AI-generated code, CI/CD pipeline compromise, secrets exposure, and software supply chain malware.
Modern AppSec programs increasingly combine OWASP guidance with software supply chain security, AI security, and runtime risk analysis to address evolving attack surfaces.
