## Critical Code Flaw: Export Handler Loads Entire Database into Memory, Risking Server Crash
A critical vulnerability in the export handler of a server application poses an immediate risk of Out-Of-Memory (OOM) crashes and Denial of Service (DoS). The flaw, located in the `internal/handlers/export.go` file, loads the entire contents of multiple database tables directly into system memory without any pagination or size limits. This design guarantees that a single administrative export request will exhaust server resources, leading to a complete crash.

The handler's code explicitly loads all records sequentially: all users on line 103, all rooms on line 116, all categories on line 130, all messages on line 141, and all invites on line 154. For any server with substantial data—particularly one storing millions of messages—this operation is a ticking time bomb. The expected behavior would involve implementing a streaming or chunked export mechanism with proper pagination to manage memory usage safely.

This flaw represents a severe operational risk, effectively creating a built-in DoS vector accessible to any user with admin export privileges. It signals a fundamental failure in handling large-scale data operations, leaving production servers vulnerable to a single request that can trigger a catastrophic failure. The absence of basic safeguards like query limits or streaming output places the stability of the entire service in jeopardy.
