CVE-2026-116178: Python Pydantic Unbounded Multimodal Range Fields
Pydantic request model $MODEL declares range-geometry fields (offset / start / index / position, length / size) as plain `int` with no `Field(ge=...)` / `Field(gt=...)` constraint. When this schema validates remote request bodies, a client can supply negative offsets or zero/negative lengths that slip past downstream arithmetic bounds checks (Python negative
