AK🚨 React is NOT as safe as you think.
A CVSS 10.0 critical vulnerability showed how a simple JavaScript object can abuse React’s internals and lead to serious security issues in certain setups.
Yes, in the worst case:
0. Servers running React / Next.js can be compromised
1. File systems can be accessed
2. Secrets and keys can be stolen
3. Any code/command can be executed on the server
This issue originates from React Server Components and how data is processed internally.
This post isn’t enough to explain the full impact.
So I’ve created a detailed YouTube video where I:
0. Break down the vulnerability step by step
1. Explain why this happens
2. Show a live working attack demo 🔥

If you work with React or Next.js,
this is important knowledge,
watch the video now.
Cheers,
Akshay Saini 🚀

ARReact2Shell
React2Shell is a CVSS 10.0 vulnerability which allowed RCE (remote code execution) on servers using React Server Components. I’m sure many of you got emails from Vercel about this. #coding #programming #javascript #react2shell

ALReact just got a CVSS 10/10 vulnerability — maximum severity! 😱💥 Server components can be remotely exploited via malicious React Flight payloads.
React Flight serializes server-built UI to browser, but deserializes untrusted input without validation. Attackers craft payloads that execute arbitrary code on your server — no login needed, just one poisoned request triggers RCE during deserialization. 🕷️
Check your packages NOW, patch immediately. Backend devs are sweating — this explains the extra coffee consumption! ☕⚠️

THCVSS tells you how bad. EPSS tells you how likely.
Security teams have long relied on CVSS to assess vulnerability severity. But attackers don’t care about theoretical scores — they exploit what’s easiest.
That’s where EPSS comes in:
⚡ A predictive model updated daily to estimate the likelihood of exploitation.
✅ Use CVSS for impact
✅ Use EPSS for probability
✅ Add CISA KEV for confirmation
🧠 At Attaxion, we combine all three so you can focus on vulnerabilities that actually matter.

SE🚨 CVSS Scores: A Broken System? 💻⚠️ 🚨
Cybersecurity professionals rely on CVSS scores to assess vulnerabilities, but what if the system itself is flawed? 🤯 Daniel Stenberg dives into the gaps in CVSS calculations, questioning why some critical risk factors are completely ignored. When the numbers don’t match reality, can we really trust them? Watch to find out! 👀

WO🔒 What is CVSS? (Bug Bounty Basics)
Ever wondered how security researchers decide how serious a vulnerability is? That’s where CVSS — the Common Vulnerability Scoring System — comes in.
In this Reel, our Wordfence Threat Intelligence team breaks down:
✅ What CVSS means in plain language
✅ How vulnerabilities are scored (exploit complexity, required permissions, remote vs. local access)
✅ Why the CIA triad — Confidentiality, Integrity, Availability — matters for every vulnerability
✅ Why CVSS gives a high-level view, but full vulnerability reports are essential
Whether you’re a WordPress site owner, security researcher, or just curious about bug bounties, this quick breakdown will help you understand how risks are scored and why it matters.

CY🔥 CYBER NEWS ALERT:
Cisco Patches CVE-2025-20188 (10.0 CVSS) in IOS XE That Enables Root Exploits via JWT.
🚨 Cisco has released software fixes to address a maximum-severity security flaw in its IOS XE Wireless Controller that could enable an unauthenticated, remote attacker to upload arbitrary files to a susceptible system.
The vulnerability, tracked as CVE-2025-20188, has been rated 10.0 on the CVSS scoring system.
"This vulnerability is due to the presence of a hard-coded JSON Web Token (JWT) on an affected system,"
📍"An attacker could exploit this vulnerability by sending crafted HTTPS requests to the AP image download interface. A successful exploit could allow the attacker to upload files, perform path traversal, and execute arbitrary commands with root privileges."
__ That said, in order for the exploitation to be successful, the Out-of-Band AP Image Download feature must be enabled on the device. It's disabled by default.
⚔️ While updating to the latest version is the best course of action, as temporary mitigations, users can disable the feature until an upgrade can be performed.
"With this feature disabled, AP image download will use the CAPWAP method for the AP image update feature, and this does not impact the AP client state," Cisco added. #Cisco #cybersecurity #stayinformed #stayahead
