CVE-2026-37552

Unsafe Deserialization in MixPHP Framework 2.x Allows Arbitrary Code Execution via TCP

Published May 1, 2026 CVSS 3.1 · 8.4 High EPSS < 1% KEV · Not listed
Description
Unsafe deserialization vulnerability in MixPHP Framework 2.x thru 2.2.17. The sync-invoke TCP server (Server.php:87) receives data from a TCP socket, passes it directly to Opis\Closure\unserialize(), then executes the result via call_user_func(). No authentication or signature verification exists on the TCP connection. An attacker with access to the localhost TCP port (server binds 127.0.0.1) can send a crafted serialized PHP closure to achieve arbitrary code execution.
