TL;DR: On October 22, 2026, Zero Day Initiative accidentally posted six unpatched Linux kernel vulnerabilities to the public LKML. Two are CVSS 9.0 SMB RCEs; three are local privilege escalation. No mainline patches exist yet. Monitor your distribution and unload exposed modules.

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.
