PHP2Shell exploit bypasses protections designed to stop remote code execution
Researchers at VulnCheck developed an exploit that bypasses Address Space Layout Randomization (ASLR) protections to achieve remote code execution against CVE-2026-109618 and CVE-2026-109619, two critical PHP vulnerabilities disclosed October 22, 2026. The exploit chains a memory leak to achieve RCE on PHP 8.4.26 with ASLR enabled and production configurations, overcoming a major barrier that had previously blocked practical attacks on real-world systems. The finding underscores that artificial intelligence (AI) is accelerating adversary exploit development and that memory protections alone cannot stop determined attackers.
Why it matters: Organizations running vulnerable PHP versions must patch immediately, as ASLR and configuration hardening are no longer reliable defenses against PHP2Shell exploitation in production environments.
