On October 21, 2026, PHP released security updates for two critical remote code execution (RCE) vulnerabilities, CVE-2026-109618 and CVE-2026-109619, associated with the PHP2Shell security issue. Both vulnerabilities have a CVSS v4.0 score of 9.2, indicating a high level of risk for affected PHP environments.<\/span><\/p>

These vulnerabilities can allow attackers to execute commands on a server through specially crafted HTTP requests. A key concern is that exploitation may occur before the website\u2019s application code runs, meaning application-level authentication alone may not prevent an attack.<\/span><\/p>

For businesses running PHP-based websites, including WordPress sites, the priority is to identify affected PHP environments, apply the appropriate security patches, and investigate suspicious activity. Updating themes and plugins alone will not fix a vulnerability in the underlying PHP runtime.<\/span><\/p>
