PHP2Shell Exploited Pre-Patch and ConnectWise Breach Hits 2,250 Tenants
Description
PHP2Shell Exploited Pre-Patch and ConnectWise Breach Hits 2,250 Tenants
Two major threats demand immediate attention from UK small businesses today. First, critical PHP vulnerabilities CVE-2026-109618 and CVE-2026-109619 were actively exploited four days before patches existed. Amazon’s threat intelligence detected deliberate, pre-disclosure attacks from 17 October, with Cloudflare recording millions of exploit attempts by the time fixes arrived on 21 October. These remote code execution flaws affect the PHP installations powering most UK SMB web infrastructure, including WordPress, WooCommerce and Magento. Second, Microsoft confirms a Chinese state-linked actor exploited ConnectWise infrastructure to access 2,250 cloud tenants. The breach compromised remote monitoring platforms used by UK managed service providers, with attackers achieving privileged access in under three hours using AI-assisted techniques. If your business uses an MSP, there is material probability your provider relies on ConnectWise tooling that grants administrative access to your endpoints, email and backups. Also covered: a maximum severity GitLab remote code execution flaw requiring immediate patching, and The Gentlemen ransomware group surpassing 800 claimed victims. Today’s action items are direct: verify your PHP version was updated after 21 October, and confirm whether your IT provider uses ConnectWise and what incident response they conducted.
