Interactive hands-on labs covering the OWASP Top 10 2025. Learn web application security through real-world attack simulations and defense strategies.
10 of 10 interactive labs now live. Explore attack simulations, code examples, and defense strategies for every OWASP Top 10 category.
Restrictions on authenticated users are not properly enforced. Attackers can exploit flaws to access unauthorized functionality and data.
94% of apps testedMissing security hardening, default credentials, open cloud storage, verbose errors, and unnecessary features enabled.
Moved up from #5Compromised dependencies, tampered build systems, malicious packages. NEW category expanding on vulnerable components.
NEW in 2025Failures related to cryptography which often lead to sensitive data exposure. Weak ciphers, hardcoded keys, poor TLS.
Formerly Sensitive Data ExposureSQL, NoSQL, OS, LDAP injection. User-supplied data is not validated, filtered, or sanitized by the application.
Dropped from #3Missing or ineffective security controls. Flaws in design and architecture that cannot be fixed by implementation.
Design-level flawsBroken authentication mechanisms allowing attackers to compromise passwords, keys, session tokens, or user identities.
Identity compromiseCode and infrastructure that does not protect against integrity violations. CI/CD pipelines, auto-updates, deserialization.
Trust boundary failuresInsufficient logging, detection, monitoring, and active response. Attacks go undetected without proper observability.
Detection gapsImproper error handling, logical errors, and issues from abnormal conditions. NEW category for edge case failures.
NEW in 2025Hands-on attack and defense simulations for each OWASP vulnerability type.
Side-by-side code comparisons showing vulnerable patterns and secure fixes.
OWASP-recommended mitigations, checklists, and security best practices.
