Prior to 7.7.0, GET /docs/api exposes the Scramble-generated OpenAPI documentation configured by config/scramble.php to unauthenticated callers after installation, with observed response size and latency suggesting that the schema is regenerated without an application-level cache. A remote attacker can repeatedly request the unthrottled route to consume server CPU and obtain a detailed map of the API surface and parameter schema.
