Vulnerability Instance

aiograpi has dependency on vulnerable orjson 3.11.4 (CVE-2025-67221)
## Impact

aiograpi 0.6.6 / 0.7.0 / 0.7.1 declared `orjson==3.11.6` (and later `==3.11.8`) in `requirements.txt` but `setup.py` carried a hard-coded duplicate `requirements = [...]` list that was never updated and still pinned `orjson==3.11.4`.

When `setuptools` builds the source distribution it reads the metadata from `setup.py`, not from `requirements.txt`. So `pip install aiograpi==0.6.6` (or 0.7.0 / 0.7.1) actually pulls `orjson==3.11.4` — a version vulnerable to **CVE-2025-67221** (stack overflow in `orjson.dumps` on deeply nested JSON inputs).

## Practical exploitability

Low in the typical aiograpi flow: `orjson` is used to encode request bodies aiograpi itself constructs and to decode responses returned by Instagram. An attacker would need to coerce aiograpi to encode an attacker-controlled deeply-nested Python structure or to decode an attacker-supplied stream — not the normal call shape.

However any caller doing `client.public_request(...)` or similar with caller-controlled payloads, or any caller passing aiograpi-decoded `last_json` into recursive serialization, may hit the unbounded recursion. The patched orjson rejects deeply-nested inputs cleanly.

## Patches

Fixed in **aiograpi 0.7.2** by migrating to `pyproject.toml` (PEP 621) — single source of truth for dependencies. PyPI installs of 0.7.2 and later resolve `orjson==3.11.8` correctly.

## Workarounds

Force-install a non-vulnerable orjson alongside the affected aiograpi version:

```
pip install 'aiograpi==0.7.1' 'orjson>=3.11.6'
```

Or just upgrade to a fixed aiograpi:

```
pip install -U 'aiograpi>=0.7.2'
```
