I Built an Emergency Toolkit for PHP2Shell RCE (CVE-2026-109618) - From Pakistan

Description and use

An emergency toolkit was built to detect and mitigate the PHP2Shell RCE vulnerability (CVE-2026-109618) on shared hosting servers, enabling non-root users to apply patches via .htaccess or php.ini.

Problem

A critical PHP vulnerability (PHP2Shell, CVE-2026-109618) allows remote code execution via malicious EXIF headers, leaving many shared hosting servers in Pakistan unpatched.

Outcome

The toolkit successfully scans for PHP2Shell vulnerabilities and applies an immediate mitigation patch, protecting shared hosting servers from RCE without requiring root access.

Workflow

• Clone the toolkit repository: git clone https://github.com/farimazhar/php2shell-fix-toolkit
• Navigate into the directory: cd php2shell-fix-toolkit
• Run the scanner against the web root: ./scan.sh /var/www/html
• Apply the mitigation: ./fix.sh --apply

Evidence

When I saw a new critical PHP vulnerability PHP2Shell (CVE-2026-109618) with CVSS 10.0 allowing RCE via EXIF headers, I knew many shared hosting servers in Pakistan would remain unpatched.
