CVE-2026-23524— Laravel Redis Horizontal Scaling Insecure Deserialization

Laravel Redis Horizontal Scaling Insecure Deserialization

Laravel Reverb provides a real-time WebSocket communication backend for Laravel applications. In versions 1.6.3 and below, Reverb passes data from the Redis channel directly into PHP’s unserialize() function without restricting which classes can be instantiated, which leaves users vulnerable to Remote Code Execution. The exploitability of this vulnerability is increased because Redis servers are commonly deployed without authentication, but only affects Laravel Reverb when horizontal scaling is enabled (REVERB_SCALING_ENABLED=true). This issue has been fixed in version 1.7.0. As a workaround, require a strong password for Redis access and ensure the service is only accessible via a private network or local loopback, and/or set REVERB_SCALING_ENABLED=false to bypass the vulnerable logic entirely (if the environment uses only one Reverb node).

可信数据的反序列化

Laravel Reverb 代码问题漏洞

Laravel Reverb是The Laravel Framework开源的一个库。为Laravel应用程序带来了实时WebSocket通信。 Laravel Reverb 1.6.3及之前版本存在代码问题漏洞，该漏洞源于数据未经限制直接传递给反序列化函数，可能导致远程代码执行。
