What A04:2025 Cryptographic Failures requires
OWASP Top 10:2025 A04:2025 Cryptographic Failures. Moving down two positions to #4, this weakness focuses on failures related to the lack of cryptography, insufficiently strong cryptography, leaking of cryptographic keys, and related errors. This category sits within the OWASP Top 10:2025 (the 2025 edition, finalized January 2026), the canonical industry list of the ten most critical web application security risks. Organizations building web applications should treat each of the ten categories as both a design constraint and a continuous-monitoring obligation, with policies, automated testing, and incident response procedures defined per category. Mapped weaknesses: CWE-261, CWE-296, CWE-319, CWE-320, CWE-321, CWE-322, CWE-323, CWE-324, CWE-325, CWE-326, CWE-327, CWE-328, and others.
