Top 10 Website Vulnerabilities in 2026

The Evolution of Cyber Threats

As web technologies evolve, so do the tactics of malicious actors. In 2026, we are seeing a massive shift towards AI-driven credential stuffing and logic flaws that traditional firewalls struggle to detect.

1. Broken Access Control

Still reigning supreme, broken access control allows attackers to bypass authorization protocols and elevate their privileges.

2. Cryptographic Failures (Missing SSL)

Transmitting data over HTTP or using deprecated TLS 1.0/1.1 protocols exposes sensitive user data to Man-In-The-Middle (MITM) attacks.

3. Injection Flaws

SQL Injection, NoSQL Injection, and Command Injection remain prevalent. Always use parameterized queries and strict input validation.

Automate your defense strategy by integrating a continuous vulnerability scanner like FortPilot Pro into your CI/CD pipeline.
