asobi_body_cap_plugin (asobi v0.75.1)

View Source

Pre-request plugin that caps HTTP request body size.

Runs before nova_request_plugin so we can short-circuit oversized requests with 413 before any body bytes are buffered into BEAM heap.

H2 (2026-05-19): without this cap, an authenticated client could POST a multi-GB JSON body to any /api/v1/** endpoint and OOM the node before the controller's per-route check (e.g. MAX_SAVE_DATA_BYTES) ever ran.

Options: max_body => non_neg_integer() %% bytes, default 1 MiB require_content_length => boolean()%% reject chunked w/o content-length, default true
