CVE-2026-109618 & CVE-2026-111497: PHP & Node.js Bug Fixing Services by Mehta WebSolution

Critical core-level vulnerabilities have been disclosed across both the PHP and Node.js runtime engines:

CVE-2026-109618 (PHP PHP2Shell OOM Memory Corruption): Enables unauthenticated Remote Code Execution (RCE) during out-of-memory request cleanups before application code executes.
CVE-2026-111497 (Node.js Node2Shell Brotli Decoder Flaw): An out-of-bounds write vulnerability in the bundled Brotli decompression module that allows attackers to trigger heap corruption and remote code execution through malformed HTTP inputs or compressed payloads.

Because both of these flaws exist directly within the underlying runtime binaries (PHP-FPM, Node.js runtime) rather than in your application code, standard CMS updates, npm package audits, or code-level changes will not protect your servers.

If your backend environments have not been directly updated to verified engine releases, your business infrastructure is actively exposed to unauthorized system compromise.

Is Your Server Infrastructure Exposed?

Both runtime vulnerabilities impact millions of active web applications, REST APIs, and microservices worldwide:

PHP Risk Scope: Affects all unpatched PHP versions across active and legacy branches (PHP 5.4 through 8.5.11) running on Apache, Nginx (PHP-FPM), LiteSpeed, or containerized setups. Safe releases require immediate updates to PHP 8.5.12, 8.4.27, 8.3.36, or 8.2.35.
Node.js Risk Scope: Affects major Node.js deployment branches handling compressed request streams, fetch() calls, or node:zlib operations. Safe releases require immediate runtime upgrades to Node.js 26.12.1, 24.22.1, or 22.x patched builds.
