Deleted S3 buckets don't disappear from your codebase or DNS records. Attackers can register the same bucket name and silently serve malicious content under your domain. Here's how to find and fix every dangling reference before someone exploits it.
Your HTML sanitizer has an allowlist. You trust it. But stored XSS still lands in production — because allowlists are only as good as their edge-case handling. Here's exactly where they fail and how to close the gaps.
ChatGPT's default CORS configs reach for wildcards the moment the prompt gets vague — and wildcards in production are a real security problem. Here's how to prompt precisely and get configs you can actually ship.
File upload endpoints are a reliable attack surface. Path traversal lets attackers overwrite server files; MIME spoofing sneaks malicious content past your type checks. Here's how to close both holes properly.
WebSockets skip the browser's same-origin policy for connections — and attackers exploit that gap to send commands or steal data through a victim's live socket. Here's how the attack works and exactly how to stop it.
Your HMAC signature check looks correct, but if it uses a plain equality operator, an attacker can measure response times to forge tokens byte by byte. Here's how timing attacks work and how to fix them in every major language.
RBAC looks solid on paper, but subtle misconfigurations regularly leave admin routes, API endpoints, and sensitive settings open to users who should never see them. Here's how to find and fix the gaps before an attacker does.
IDOR vulnerabilities let attackers swap an ID in a URL and access someone else's data. They're easy to miss in code review and devastatingly simple to exploit. Here's how to find them, fix them, and keep them out of production.
Storing JWTs in localStorage feels convenient until an XSS vulnerability exposes every token on your site. Here's how to migrate your authentication to HttpOnly cookies — and why it matters more than you think.
XXE vulnerabilities let attackers read local files, trigger SSRF, and even crash your server — all by slipping a malicious entity into an XML document. Here's how to find XXE flaws and close them for good.
ORMs like Django ORM, SQLAlchemy, and Hibernate give you a comfortable safety net — but that net has holes. Here's exactly where raw SQL sneaks back into ORM-heavy projects and how to close those gaps before an attacker finds them.
