Lifecycle Timeline
3DescriptionGitHub Advisory
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).
AnalysisAI
Laravel Reverb WebSocket server versions 1.6.3 and below have an insecure deserialization vulnerability enabling remote code execution on the backend server.
Technical ContextAI
Laravel Reverb <= 1.6.3 deserializes untrusted data from WebSocket messages (CWE-502), allowing attackers to craft serialized PHP objects that execute arbitrary code during deserialization.
RemediationAI
Update Laravel Reverb to version 1.6.4 or later. Implement input validation on WebSocket messages.
