CyberRota Analysis
AI-GeneratedThe Maravel PHP framework prior to version 10.73.1 is vulnerable to a side-channel information disclosure issue that allows attackers to exploit dynamic route placeholders. By sending requests with literal template syntax, attackers can trigger a 500 Internal Server Error, enabling them to infer sensitive internal route parameter names and controller schemas. Developers using this framework should prioritize upgrading to the patched version or implementing defensive checks in middleware to mitigate the risk.

Original NVD 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.
