PHP2Shell is a pair of critical flaws in the PHP interpreter itself, each with a CVSS v4.0 score of 9.2. Both let an unauthenticated attacker run code on a web server with a single crafted web request, or a pair of them, before any application code runs. Because the bug lives in PHP, not in WordPress, Drupal or Magento, every reachable PHP endpoint on an affected server is exposed, including login pages, static forms, and health checks. Every PHP release from the last decade is affected (back to 5.4).

1Password Privileged Access was named an Honorable Mention in the 2026 Gartner Magic Quadrant for Privileged Access Management.

Today, Cloudflare is launching a post-quantum geographically restricted key manager in support of our Data Localization Suite (DLS) in closed beta. This new PQ GeoKey Manager is a cornerstone of Cloudflare’s data sovereignty solutions, making sure that a customer's decryption keys are only accessible in their chosen geography. GeoKey Manager implements this by wrapping each decryption key such that it can only be decrypted by Cloudflare servers that are located in the allowed geography.

Phishing attacks are increasingly using legitimate calendar invites to bypass security filters, according to researchers at Netcraft. Attackers send ICS calendar invite files that plant phishing lures directly on users’ calendars, often under the guise of work-related meetings.

The U.S. FBI and the Cybersecurity and Infrastructure Security Agency (CISA) have issued joint advisories warning of election-themed scams targeting voters and spear phishing attacks targeting election officials.

SIEM-less security may sound like an escape from traditional SIEM complexity and costs, but the underlying capabilities still have to exist somewhere. A SIEM is a multipurpose tool. It brings together cyber and physical security use cases; drives threat detection, investigation, and response (TDIR); serves as a system of record for governance, regulatory, and compliance needs; and supports observability use cases tied to resilience and service degradation. The list goes on.

On October 21, 2026, Node.js fixed CVE-2026-111497, now known as Node2Shell. The bug is in its bundled Brotli decoder, the component that unpacks compressed data. A crafted compressed stream makes the decoder write data outside the memory set aside for it, known as an out-of-bounds write. That can overwrite data the application relies on, so an attacker can crash the application, leak memory or run attacker code. Public proof-of-concept code was published within 24 hours.

AI has removed the skill, personalization, and speed barriers that once limited cyberattacks. Attackers use language models at every stage of the kill chain, from recon to persistence, and underground tools sell pre-jailbroken access to mainstream models for as little as $50 a week. But because every attack still has to change a file, a configuration, or a script on a real system, detecting unplanned change works no matter which model wrote the payload.
