Associated Vulnerability
Title:Internet Brands vBulletin 安全漏洞 (CVE-2025-48827)
Description:vBulletin 5.0.0 through 5.7.5 and 6.0.0 through 6.0.3 allows unauthenticated users to invoke protected API controllers' methods when running on PHP 8.1 or later, as demonstrated by the /api.php?method=protectedMethod pattern, as exploited in the wild in May 2025.
Description
vBulletin 5.0.0 through 5.7.5 and 6.0.0 through 6.0.3 contain an authentication bypass caused by unauthenticated access to protected API controllers on PHP 8.1 or later, letting unauthenticated attackers invoke protected methods remotely.Starting from PHP 8.1, due to an internal adjustment to handling of ReflectionMethod::invoke() and similar methods, it now allows — by default — invocation of protected / private methods when using PHP's Reflection API.
