Emergency Notice: Critical PHP Security Vulnerability (PHP2Shell)

【System Security Risk Warning · Emergency Response Notice】
Alert Time: October 22, 2026
Vulnerability Advisory: PHP High-Risk Remote Code Execution (RCE) Vulnerability, Vulnerability ID: PHP2Shell, CVE IDs: CVE-2026-109618, CVE-2026-109619, CVSS Score: 9.2, Risk Level: Critical

This vulnerability allows attackers to execute remote code, posing severe security risks including server intrusion, business data tampering, sensitive information leakage, and server compromise.
The risk scope is not limited to standalone PHP environments: mainstream CMS and web frameworks such as WordPress, Drupal, Joomla, Magento, and Laravel run on PHP. Many server control panels and third-party business components embed PHP runtime environments, resulting in a substantially wider range of affected assets. Please conduct a comprehensive check.

After the vulnerability details are disclosed, hacker scanning tools and mass exploitation scripts will spread rapidly. The window between vulnerability disclosure and large-scale exploitation is extremely short. Please initiate emergency remediation as soon as possible.

Important Note: The WAF capability bundled with our DDoS protection service serves only as a temporary mitigation measure. It can block known attack payloads and buy remediation time before the vulnerability is fully fixed, and cannot replace root-cause remediation such as official patching and code fixes.

Please contact your dedicated security support promptly if you require emergency security assessment, expedited configuration of temporary protection policies, or vulnerability asset scanning support.
Reminder: If your security operation & maintenance service is nearing expiry, we recommend renewal at your earliest convenience to sustain emergency response and security protection capabilities. Service interruption may prevent timely vulnerability handling and lead to business security incidents.
For inquiries, please reach out to your dedicated support contact immediately.
