About FailleWeb

FailleWeb is an independent media outlet dedicated to the latest vulnerabilities and security flaws affecting web applications. Every day, we decode critical CVEs, emergency patches and best practices to give developers, administrators and security officers a clear and reliable watch.

Our mission

Web application security evolves every day: between advisories from the NVD, CERT-FR, Patchstack, framework vendors and independent researchers, it has become impossible to keep track of everything. FailleWeb exists to solve this problem: cut through the noise, prioritise the flaws that truly matter and explain how to protect yourself from them.

We continuously monitor official sources — NVD, CERT-FR, Patchstack, WPScan, Snyk, GitHub Security Advisories, vendor blogs (cPanel, OpenSSH, kernel.org, Laravel, Symfony, Google Chrome) — to identify vulnerabilities with real impact and present them to you with context, criticality and remediation.

Our sections

  • CVE — Critical CVE vulnerabilities from the NVD catalogue, decoded
  • WordPress — Plugin, theme and core WordPress flaws
  • Frameworks — Laravel, Symfony, Rails, Django, Express, Spring
  • Browsers — Chrome, Firefox, Safari: 0-days and urgent patches
  • Servers — Linux kernel, cPanel, OpenSSH, Apache, nginx, panels
  • Best practices — OWASP, hardening, secrets management, code audit

Our approach

We always favour primary sources: the NVD for CVEs, advisories from the vendors themselves, kernel.org for Linux, patch commits on GitHub. For every vulnerability we cover, we systematically document the affected versions, the technical vector, the concrete impact and the remediation procedure — with links to the official patches.

No sensationalism. A CVSS 9.8 flaw is not necessarily exploitable in practice, and a CVSS 5 flaw can be trivial to exploit on your stack. We provide the nuances that let a dev or an ops decide in 60 seconds whether the update can wait until Monday or must be applied immediately.

The team

FailleWeb is run by Lucas Béranger, a cybersecurity analyst specialising in web application security for over ten years. A former PHP/Node developer turned security consultant, Lucas puts his expertise at the service of accessible coverage of web flaws for a broad audience.
