What is CVE-2026-37552?
CVE-2026-37552 is a high-severity unsafe deserialization vulnerability in n/a, published on 1 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
