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."}], "source": {"advisory": "GHSA-v2qf-qw42-8r3x", "discovery": "UNKNOWN"}}}}
