CVE-2026-37552 (GCVE-0-2026-37552)

Vulnerability from cvelistv5 – Published: 2026-05-01 00:00 – Updated: 2026-05-01 19:45
VLAI
Summary
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.
