## 2. Detailed Findings by Package

### 2.1 FastAPI (≥0.135.0)

**Core FastAPI**: No CVEs affecting the main FastAPI package in 2025–2026.

**Related packages** (if used):
- **CVE-2026-23996** (FastAPI Api Key): Timing side-channel in `verify_key()`; update to ≥1.1.0.
- **CVE-2026-2978** (FastApiAdmin): Unrestricted file upload; update to ≥2.2.1.
- **CVE-2025-68481** (fastapi-users): OAuth CSRF; update to ≥15.0.2.

**Recommendation**: No change for core FastAPI. If using FastAPI Api Key, FastApiAdmin, or fastapi-users, upgrade those packages.

---

### 2.2 uvicorn

**CVE-2025-43859** (transitive via h11):
- **Severity**: Critical (CVSS 9.1)
- **Cause**: h11 <0.16.0 lenient parsing of chunked-encoding line terminators → HTTP request smuggling
- **Impact**: Security bypass, cache poisoning, session hijacking, data leakage
- **Fix**: Pin `h11>=0.16.0`. Uvicorn PR #2621 bumps h11 (merged May 2025).

**Recommendation**: Pin `h11>=0.16.0` in requirements. Use a uvicorn release that depends on h11 ≥0.16.0.

**Sources**: [NVD CVE-2025-43859](https://nvd.nist.gov/vuln/detail/CVE-2025-43859), [Uvicorn PR #2621](https://github.com/encode/uvicorn/pull/2621)

---

### 2.3 ONNX Runtime

**AIKIDO-2026-10185** (path traversal in model loading):
- **Affected**: ONNX Runtime 1.21.0–1.24.0
- **Issue**: External data references in TensorProto can use absolute paths or `../` traversal
- **Impact**: Load unintended files, data disclosure, unexpected behavior
- **Fix**: Upgrade to ONNX Runtime ≥1.24.1

**CVE-2025-51480** (ONNX library `save_external_data`):
- **Affected**: ONNX 1.17.0
- **Issue**: Path traversal in `save_external_data` → arbitrary file overwrite
- **Fix**: ONNX patches in PR #7040; use patched ONNX.

**Recommendation**: Use ONNX Runtime ≥1.24.1. Ensure ONNX dependency is patched for CVE-2025-51480.

### 2.4 aiohttp

**Multiple CVEs fixed in 3.13.3** (released Jan 5, 2026):

| CVE | Severity | Issue |
|-----|----------|-------|
| CVE-2025-69223 | High | Zip bomb DoS via compressed request |
| CVE-2025-69228 | High | Large payload DoS (e.g. `Request.post()`) |
| CVE-2025-69227 | High | DoS via bypassed asserts when `PYTHONOPTIMIZE=1` |
| CVE-2025-69229 | Medium | Chunked message DoS (CPU exhaustion) |
| CVE-2025-69230 | Low | Cookie parser warning storm |
| CVE-2025-69226 | Low | Static file path brute-force |
| CVE-2025-53643 | — | HTTP request smuggling (fixed in 3.12.14) |

**Recommendation**: Upgrade to aiohttp ≥3.13.3.

---

### 2.5 python-jose (JWT)

**Maintenance**: Effectively unmaintained; minimal activity for ~2 years. Current version 3.5.0.

**Known CVEs**:
- CVE-2024-29370: DoS via malicious JWE (5.3 Medium)
- CVE-2024-33663: Algorithm confusion with OpenSSH ECDSA keys (6.5 Medium)
- CVE-2024-33664: JWT bomb via compressed JWE (5.3 Medium)
- CVE-2025-61152: `alg=none` (disputed by maintainers)

**Unfixed 2026 issues** (per GitHub #398):
- DER key algorithm confusion
- Missing algorithm whitelisting
- Timing side-channels

**Recommendation**: **Replace with PyJWT**. Okta and others have migrated away from python-jose. PyJWT is actively maintained and has stronger security defaults.

**Sources**: [OpenCVE python-jose](https://app.opencve.io/cve/?vendor=python-jose_project), [Okta migration issue](https://github.com/okta/okta-jwt-verifier-python/issues/54), [python-jose #398](https://github.com/mpdavis/python-jose/issues/398)

### 2.6 PyTorch (≥2.10.0)

**CVE-2026-24747** (fixed in 2.10.0):
- **Severity**: High (CVSS 8.8)
- **Issue**: `weights_only` unpickler memory corruption via crafted `.pth` checkpoints
- **Impact**: RCE when loading malicious checkpoint with `torch.load(..., weights_only=True)`
- **Fix**: PyTorch ≥2.10.0

**CVE-2025-32434** (fixed in 2.6.0):
- **Severity**: Critical (CVSS 9.8)
- **Issue**: RCE via `torch.load(..., weights_only=True)` despite documentation
- **Fix**: PyTorch ≥2.6.0

**Recommendation**: Keep PyTorch ≥2.10.0. No new CVEs found after 2.10.0. Continue using `weights_only=True` and SHA256 checksums for weights.

---

### 2.7 Pillow (≥11.3.0)

**CVE-2026-25990** (PSD out-of-bounds write):
- **Affected**: 10.3.0 through before 12.1.1
- **Severity**: High (CVSS 7.5)
- **Issue**: Out-of-bounds write when loading crafted PSD images
- **Impact**: Memory corruption, possible RCE, crashes
- **Fix**: Upgrade to Pillow ≥12.1.1

**CVE-2025-48379** (DDS buffer overflow, fixed in 11.3.0):
- Already mitigated by Pillow ≥11.3.0.

**Recommendation**: **Upgrade to Pillow ≥12.1.1** to address CVE-2026-25990.

**Sources**: [NVD CVE-2026-25990](https://nvd.nist.gov/vuln/detail/CVE-2026-25990), [GitLab Advisory](https://advisories.gitlab.com/pkg/pypi/pillow/CVE-2026-25990/)

---

### 2.8 GTSAM (4.2)

**Findings**: No CVEs or known security issues for GTSAM 4.2 in public databases.

**Recommendation**: No change. Monitor GTSAM security advisories and CVE feeds.

---

### 2.9 numpy

**AIKIDO-2025-10325** (heap buffer overflow):
- **Affected**: NumPy 2.2.0–2.2.5
- **Issue**: `numpy.strings.find()` incorrect allocation → heap buffer overflow
- **Fix**: Upgrade to NumPy ≥2.2.6

**CVE-2025-62608** (MLX, not NumPy): Malicious `.npy` parsing in MLX; fixed in MLX 0.29.4. NumPy itself is not directly affected.

**Recommendation**: If using NumPy 2.2.x, upgrade to ≥2.2.6. Otherwise no action.

---

### 2.10 safetensors

**Known attack vectors** (research, not formal CVEs):
- Polyglot files: Malicious data appended after valid safetensors payload
- Header bombs: Large JSON headers causing DoS
- Model poisoning: Backdoors in fine-tuned weights
- Conversion hijacking: Hugging Face safetensors conversion service compromise (Feb 2024)

**Metadata RCE (under review)**:
- Report on huntr.com (Feb 2026) and [huggingface_hub #3863](https://github.com/huggingface/huggingface_hub/issues/3863)
- Related to metadata parsing in AI/ML libraries (e.g. Hydra `instantiate()`)
- Details still limited; embargo possible until resolution

**Recommendation**: Continue using safetensors for weights (safer than pickle). Avoid parsing metadata with unsafe deserialization. Monitor safetensors and huggingface_hub advisories.

## 3. Supply Chain & Model File Attacks

### PyTorch model weights

**Known CVEs**:
- CVE-2025-32434: RCE via `weights_only=True` (≤2.5.1) — fixed in 2.6.0
- CVE-2026-24747: Memory corruption in weights_only unpickler (<2.10.0) — fixed in 2.10.0

**No additional supply chain CVEs** found beyond these. Mitigations remain:
- PyTorch ≥2.10.0
- `weights_only=True` for all `torch.load()`
- SHA256 checksums for all weights
- Prefer safetensors where available

### ONNX model files

**Path traversal**:
- AIKIDO-2026-10185 (ONNX Runtime 1.21–1.24): External data path traversal
- CVE-2025-51480 (ONNX): `save_external_data` path traversal

**Recommendation**: Use ONNX Runtime ≥1.24.1. Load only ONNX models from trusted sources; validate external data paths.
