Catatan episode
Two critical PHP vulnerabilities, CVE-2026-109618 and CVE-2026-109619, were disclosed before the patch was available, creating an urgent remote-code-execution risk for PHP-powered websites. That includes sites built with WordPress, Joomla, Drupal and Magento, along with any overlooked PHP installation still running on a server.
Peter breaks down the practical response for website owners and agencies: take fresh backups, confirm hosting and firewall protections, inventory every installed PHP version, move away from end-of-life releases and watch official PHP announcements for patched versions. He also explains the warning signs to monitor, including unusual CPU or memory use, unexpected files, web shells, cron jobs, scheduled tasks and new accounts.
If compromise is suspected, isolate the affected server, preserve web-server and PHP logs, and work with the hosting provider or a security professional before making destructive changes that could erase evidence.

What you'll learn:
- CVE-2026-109618 and CVE-2026-109619 are critical PHP remote-code-execution vulnerabilities that were disclosed before the patch was available.
- Website owners should take a fresh backup and confirm that their hosting provider will apply the relevant PHP security update.
- Server administrators should inventory every installed PHP version so forgotten or end-of-life environments are not left exposed.
- PHP 5, PHP 7, PHP 8.0 and PHP 8.1 are end-of-life branches discussed in the episode and should not be relied on for current security fixes.
- Unexpected CPU or memory spikes, uploaded files, web shells, new cron jobs, scheduled tasks or accounts may indicate malicious activity.
- A suspected compromise should be isolated while web-server and PHP logs are preserved for investigation.
- Small-business websites are operational assets, so backups, patching, monitoring and direct contact with the hosting provider should be treated as urgent work.
