Emerging Threat: (CVE-2026-23869) React Server Components Denial of Service

Apr 15, 2026 By Igal Zeifman In CyCognito
CVE-2026-23869 is a denial of service vulnerability in React Server Components, caused by improper handling of cyclic data structures during deserialization of incoming HTTP requests. The vulnerability resides in the React Flight protocol's server-side reply handling, specifically in the createMap, createSet, and extractIterator functions within ReactFlightReplyServer.js. The vulnerability carries a CVSS v3.1 base score of 7.5 (High). Exploitation requires no authentication and no user interaction.

CVE-2026-21643: Pre-Authentication SQL Injection in Endpoint Management Server Leading to Remote Code Execution

Apr 15, 2026 By foresiet In Foresiet
CVE-2026-21643 is a critical SQL injection vulnerability in the administrative web interface of FortiClient Endpoint Management Server version 7.4.4. It allows unauthenticated remote attackers to execute arbitrary SQL commands through specially crafted HTTP requests, primarily by injecting malicious payloads via the Site HTTP header.

Scaling Your Security Program to Match the Speed of Mythos

Apr 15, 2026 By Ravid Circus In Seemplicity
Anthropic’s Project Glasswing and the Claude Mythos model represents a fundamental change in the physics of cyber defense. With the gap between patch releases and weaponized exploits shrinking to hours, traditional manual security triage is now obsolete. Organizations must adopt AI-driven automated remediation.

Axios CVE-2026-40175: a critical bug that's... not exploitable

Apr 14, 2026 By Mackenzie Jackson In Aikido
It’s been a chaotic few weeks for Axios. First, a major supply chain attack put the package under scrutiny. Then, just days later, headlines started appearing about a “critical 10/10 vulnerability” that could lead to full cloud compromise. If you’ve read the coverage, you’ve probably seen claims like: That sounds bad. But when you look closely at how this vulnerability actually behaves in real environments, the story changes.

Mythos, MOAK, CTEM and the End of CVE Chasing

Apr 14, 2026 By Igal Zeifman In CyCognito
A few weeks ago the world was exposed to Mythos, Anthropic's new frontier model and the Project Glasswing announcement that came with it. The reaction across the industry was immediate. Cybersecurity stocks fell sharply. The Treasury Secretary convened an emergency meeting with major bank CEOs. 250 CISOs produced a response playbook over a single weekend. That is not a typical announcement or a PR "leak". That is a reckoning. Then, about a week later, I came across MOAK.

How We're Securing Our Own Supply Chain

Apr 13, 2026 By Lev Pachmanov In Seal Security
Building a supply chain security company comes with an uncomfortable truth: our remediated packages run inside our customers' production environments. A compromise on our end is a compromise on theirs. We take that responsibility seriously. I want to pull back the curtain on how we actually secure our own supply chain - from the code we write, to the artifacts we deliver, to the infrastructure that holds it all together. ‍

Are You Ready for the CVE Avalanche?

Apr 13, 2026 By Marc Gaffan In IONIX
What the Anthropic Mythos findings mean for every security team, and the 90-day window you cannot afford to miss. Last week, Anthropic published something that should stop every CISO in their tracks. Its Mythos Preview model, running autonomously, without expert guidance, identified thousands of high- and critical-severity vulnerabilities across major operating systems, browsers, and open-source projects.

Lightboard Lab: Closing the Valley of Visibility in Network Vulnerability Assessment

Apr 13, 2026 By CrowdStrike In CrowdStrike
Network Vulnerability Assessment is often treated as a point-in-time exercise—but real environments don’t stand still. Between long scan cycles, two things are constantly changing: network devices drift as configurations and versions evolve, and the world around them shifts as new vulnerabilities are disclosed.

I Tried 5 Prompt Injection Attacks (Here's What Happened)

Apr 13, 2026 By Snyk In Snyk
In this video, we explore the growing security risk of prompt injection in large language model (LLM) applications. As AI becomes embedded in more products, new vulnerabilities emerge, especially through natural language manipulation. We break down how LLMs work, the importance of system prompts, and demonstrate five real-world prompt injection techniques used to extract sensitive information or bypass safeguards. You’ll see live examples using different models and learn why newer models are more resilient, but still not immune.

Governing Security in the Age of Infinite Signal - From Discovery to Control

Apr 10, 2026 By Randall Degges In Snyk
Anthropic just open-sourced vulnerability discovery at scale. Now what? A few weeks ago, Anthropic launched Glasswing, a $100 million initiative to use AI to identify vulnerabilities at scale. Around the same time, they introduced Claude Mythos, a system that can autonomously discover and exploit software flaws. I wrote about this trajectory in my previous analysis: AI accelerates discovery, but enterprise trust still depends on deterministic validation, remediation automation, and governance at scale.
