Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Maravel（一个面向依赖注入的 PHP 框架）在 10.73.1 版本之前存在一个侧信道信息泄露问题。当路由使用动态占位符（例如 ）进行编译时，原始的字符串占位符键被错误地注册到了扁平的静态路由检查表中。攻击者在对端点进行扫描时，可以故意传递字面量模板语法（例如 ），从而强制与静态映射表发生意外匹配。由于动态树引擎被绕过，未捕获到任何参数。这导致现代 PHP 8+ 版本抛出原生的 ，返回 500 内部服务器错误，而非统一的 404 未找到。通过追踪哪些模糊测试模式会触发 500 错误，恶意行为者可以编程地描绘并

Vulnerability Title
Maravel-Framework Vulnerable to Side-Channel Information Disclosure (Error Oracle) via Dynamic Route Fuzzing
Source: CVE Program / CVE List V5
Vulnerability Description
Maravel, a PHP framework oriented towards dependency injection, prior to version 10.73.1 has a side-channel information disclosure issue. When a route was compiled with dynamic placeholders (e.g., `/api/v1/users/{id}`), the raw string placeholder key was mistakenly registered into the flat static route checklist. An attacker scanning endpoints could intentionally pass the literal template syntax (e.g., `GET /api/v1/users/{id}`) to force an unexpected match against the static map. Because the dynamic tree engine was bypassed, no arguments were captured. This forced modern PHP 8+ versions to throw a native `ArgumentCountError`, resulting in a 500 Internal Server Error instead of a uniform 404 Not Found. By tracking which fuzz patterns exploded into a 500 error, a malicious actor could programmatically profile and map out internal route parameter names and controller schemas. Version 10.73.1 contains a patch. As a workaround, mitigate this side-channel leak by implementing a defensive check in a global middleware. This will reject any literal brace patterns before they reach the router engine.
