CVE-2026-23524 is a critical Remote Code Execution (RCE) vulnerability affecting Laravel Reverb versions 1.6.3 and below. It arises from Reverb passing Redis channel data directly to PHP’s unserialize() function without proper class restrictions, allowing arbitrary object instantiation. This vulnerability carries a CVSS score of 9.8 (CRITICAL) due to its network attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While there is no known active exploitation or public exploit code, the vulnerability has garnered some community discussion, and its exploitability is heightened when Redis lacks authentication and Reverb’s horizontal scaling is enabled.
