Although it respected `file.size`, processing a maximum allowed payload size into memory before writing to disk could still cause memory exhaustion when under heavy load. -**Learning:** For large file uploads, loading the entire payload into a single Python object (even just to process or save it) creates a bottleneck where large chunks of contiguous memory are required simultaneously. The Strix security scanner will flag this as a Resource Exhaustion Vulnerability ("security theater") if you attempt to just bound a single `file.read()`. -**Prevention:** Stream the chunks (e.g. 8192 bytes) directly to a `NamedTemporaryFile` on disk while verifying the accumulation does not exceed the maximum allowed payload size. Ensure the temporary file is securely unlinked in a `finally` block or when an upload limit exception is raised. diff --git a/.trivyignore b/.trivyignore new file mode 100644 index 0000000..cc229a0
