PHP Security issues Black October 2026 : What is the vulnerability found in PHP software?

The global internet is currently facing a massive cybersecurity crisis due to two critical, AI-discovered remote code execution vulnerabilities in core PHP (CVE-2026-109618 and CVE-2026-109619). Coined "php2shell" by researchers, the flaws allow unauthenticated attackers to remotely take control of web servers, steal private databases, and deface websites without requiring a password.

PHP powers roughly 70% of all websites globally—including foundational systems like WordPress, Joomla, and Wikipedia—cybersecurity agencies have called this one of the largest and most dangerous vulnerabilities ever to be patched, dubbing the scramble "Black October"

What is the vulnerability found in PHP software?

PHP is a very popular programming language used to build most websites and web applications worldwide. Recently, a serious security flaw was discovered in its core architecture, creating a risk where hackers could exploit it to gain access to servers and run unauthorized commands.

News reports indicate that these vulnerabilities, hidden within the code for years, were discovered using Artificial Intelligence (AI). As soon as this security flaw became public, cyberattacks and hacking attempts intensified globally.

According to international cloud service provider Cloudflare, millions of attack attempts were recorded within 45 minutes of the vulnerability being disclosed. Technology companies including Amazon have also warned of widespread attempts to scan and exploit systems worldwide.

Its impact is being seen globally, not just in Nepal. In Japan, Nomura, Mitsubishi UFJ, ANA Airlines, and government ministries have also halted their online services.

Experts say that since the risk is high in systems running on older PHP versions, the safest option is to keep services closed until all code and servers are upgraded to new, secure versions.
