PHP developers issued a security advisory indicating that patches for two high-severity vulnerabilities would be released within approximately 12 hours of the announcement. Both vulnerabilities received severity ratings of 9.2 out of a possible 10, prompting urgent action from the maintenance team.
The advisory came after unconfirmed reports surfaced detailing what appeared to be a remote code execution exploit tool called PHP2Shell. While the original report could not be independently verified, security firm watchTowr confirmed that the vulnerabilities identified as CVE-2026-109618 and CVE-2026-109619 are genuine. The exploit was reportedly demonstrated on multiple popular platforms including WordPress, Drupal, Joomla, Laravel, and others that rely on PHP infrastructure. According to the unconfirmed details, the vulnerabilities potentially affect every version of PHP dating back to PHP 5.
Second security researchers predicted that significant attack campaigns could begin shortly after patch availability. Multiple security organizations, including Sansec, Webfence, and Huntress, issued their own advisories urging administrators to take immediate preparatory measures. These steps included identifying personnel responsible for PHP management within their organizations, conducting inventories of all applications using the language, scheduling maintenance windows, and backing up critical data before applying updates.
Given that PHP powers an estimated 1.3 million Internet-connected hosts and serves as the foundation for numerous content management systems and web applications, the scope of potential impact is substantial. PHP maintainers indicated they reserved the right to accelerate the release timeline if vulnerability details became public or active exploitation incidents were documented. Administrators were advised to monitor official PHP channels closely for any announcements regarding earlier deployment of the patches.
