Wiz: No successful PHP2Shell exploits seen so far; exposure down 67%

Last week, we published a report describing two major vulnerabilities in PHP (CVE-2026-109618, CVE-2026-109619). Since then, alongside much of the security industry, the Wiz Research team has been monitoring for related activity in the wild and reviewing publicly available exploit code. So far, we have observed a limited number of exploitation attempts in our telemetry and have not identified a publicly available proof of concept (PoC) demonstrating complete, general end-to-end exploitation against an arbitrary target. Some partners have, however, privately disclosed to us exploits that work against a variety of targets and we continue to experiment internally. Videos demonstrating our successful exploitations are available at php2shell.com .

This post summarizes what we have observed in terms of remediation efforts and exploitation attempts across real world environments and in our own honeypot data to date and shares findings from our ongoing investigation into these activities.
