Exposed API Keys and Secrets
API keys and secrets discovered in client-side code are publicly visible to anyone who visits your website. Attackers can extract these keys using browser developer tools or by viewing page source.
Hardcoded Passwords and Credentials
Hardcoded passwords in client-side code are a critical security vulnerability. These credentials are visible to anyone who views your website's source code or uses browser developer tools.
Insecure Forms and Data Submission
Forms that submit sensitive data over insecure connections or lack proper security controls can expose user information to attackers. This includes password fields over HTTP, missing CSRF protection, and inadequate input validation.
Missing Security Headers
Security headers are HTTP response headers that tell browsers how to behave when handling your site's content. Missing or misconfigured headers can leave your site vulnerable to various attacks.
Known Vulnerabilities (CVEs)
Common Vulnerabilities and Exposures (CVEs) are publicly disclosed security flaws in software. Your website is using software versions that contain known security vulnerabilities.
Mixed Content (HTTP on HTTPS)
Mixed content occurs when an HTTPS page loads resources (scripts, images, stylesheets) over insecure HTTP. This creates a security vulnerability even though the main page is encrypted.
Development Artifacts and Debug Information
Development artifacts like .env files, debug modes, console logs, and internal IP addresses accidentally left in production code can leak sensitive information about your infrastructure.
