If your architecture is protected by a FortiGate firewall, runs Nginx routing traffic to PHP, Go, and Node.js (plus that random Java service someone forgot to decommission), is hosted on Linux, uses LiteLLM for AI, deploys through self-hosted GitLab, and relies on a questionable eMudhra HTTPS trust chain…

Congratulations! 🎉 You’ve unlocked the Vulnerability Full Course Meal for this month. 💀

Today’s Special
#

Today’s menu features a little bit of everything:

  • 🥗 PHP & Node.js — The Starter: Deserialization surprises, memory-handling nightmares, and Brotli buffer corruption.

  • 🍲 Java & Go — The Soup: JSSE certificate-validation bypasses, unauthenticated remote code execution, and HTTP/3 denial-of-service attacks.

  • 🥩 LiteLLM & Nginx — The Main Course: SQL injection, server-side template injection, path traversal, and SSRF. Because apparently, your attack surface wasn’t big enough already.

  • 🍰 GitLab & eMudhra — The Dessert: CI/CD remote code execution and compromised certificate authority trust. Nothing says zero trust quite like trusting the wrong thing.

And the best part? All of this sits on top of an OS, behind a firewall, inside an architecture someone probably described as production-ready.

With security advisories seemingly arriving faster than teams can patch, standard DevOps alone won’t save us.

It’s time to light some incense, sacrifice a stale YAML file to the server gods, and conduct a thorough architectural self-reflection. 🕯️🙏

Because in modern infrastructure, the question isn’t whether your stack has vulnerabilities.

It’s whether you’ve found them before someone else does.

📋 Bill of Materials
#

Here’s the vulnerability shopping list behind today’s full-course experience.

  1. ☕ Java (Oracle / JSSE): CVE-2026-91403, CVE-2026-114820 — Reported certificate-verification and remote security-restriction bypass issues.

  2. 🔐 eMudhra CA / HTTPS Trust: CVE-2026-111943, CVE-2026-111944 — Reported issues involving compromised intermediate CA private keys.

  3. 🐘 PHP: CVE-2026-109618, CVE-2026-109619 — Reported critical memory-handling and remote code execution vulnerabilities, dubbed PHP2Shell in this draft.

  4. 🦊 GitLab: CVE-2026-110264 — Reported as an unauthenticated regex-engine RCE with a CVSS score of 10.0; CVE-2026-97229 — CI/CD-related RCE.

  5. 🤖 LiteLLM: CVE-2026-42208 — Reported proxy API-key SQL injection; CVE-2026-37004 — Reported server-side template injection and OS command execution.

  6. 🟢 Node.js: CVE-2026-111497 — Reported Brotli decoder out-of-bounds write with potential code-execution implications.

  7. 🚀 Go Ecosystem: CVE-2025-64702 — Reported quic-go QPACK-related memory-amplification denial of service.

  8. 🧱 Fortinet (FortiGate / FortiOS): CVE-2025-25249 — Reported FortiGate exploitation involving deployment of custom Node.js malware. Because even the firewall can become part of the attack surface, the appetizer comes with a side of perimeter compromise. CVE-2026-106174 — FortiOS HTTPS management-interface denial of service.
