Two separate security problems are affecting web servers using PHP and WordPress. The PHP project issues emergency patches for two remote code execution flaws in the PHP runtime, dubbed PHP2Shell and tracked as CVE-2026-109618 and CVE-2026-109619, with a reported CVSS v4.0 score of 9.2 and the ability for unauthenticated attackers to run code on servers. Coverage also reports that attackers have used stolen UpdraftCentral connection keys to push signed commands that install backdoor plugins on connected sites.

Across outlets, governments and organizations take precautionary steps after the PHP issues are disclosed, including shutting down some websites. Several stories attribute the discovery to AI-assisted identification by security research partners, and repeatedly cite an estimate that PHP underpins about 70% of websites. Others focus on what administrators should do, emphasizing that the weaknesses can be triggered even if application code is secure and that patching and checking PHP versions and distribution backports are necessary. Some outlets highlight expert commentary, while another adds that fixes are applied and operational guidance is available.

(Angles vary between general-impact reporting and hands-on remediation framing; all sources align that the PHP vulnerabilities and related shutdowns are central to the story, while the UpdraftCentral/backdoor element appears only in the provided PHP-focused report.)
