Accidentally committing API keys, passwords, or cloud credentials to a public Git repository can expose your infrastructure within minutes. Learn how to detect leaked secrets, remove them from your repository history, rotate compromised credentials, and prevent future secret leaks
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.
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.
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.
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.
Modern applications depend on thousands of open-source packages, making software supply chains an increasingly attractive target for attackers. One of the most dangerous scenarios occurs when a trusted maintainer account is compromised and malicious code is published through legitimate release
A Content Security Policy that looks correct on paper can be trivially bypassed in practice. Learn which common CSP patterns attackers exploit and how to tighten your policy before someone else does.
GraphQL's flexibility is a double-edged sword. Introspection leaks your entire schema to attackers, and query batching can turn a single request into a denial-of-service weapon. Here's how to shut both doors.
