Summary

uv.lock currently pins cryptography==46.0.6, which is affected by CVE-2026-39892 / GHSA-p423-j2cm-9vmq.
The vulnerable release enters the runtime via transitive dependencies (google-auth and pyjwt[crypto]) used by the CleverAgents CLI, so every CLI invocation on Python 3.13 loads the flawed wheel.
Upgrade cryptography to the patched 46.0.7+ release and regenerate uv.lock, then re-run the mandated nox suites to preserve the 97% coverage threshold and CI parity.

Findings

cryptography 46.0.6 present in lockfile
- uv.lock excerpt: name = "cryptography" / version = "46.0.6" (pulled via google-auth and pyjwt).
- Python 3.13 is our target interpreter (pyproject.toml and tool.ruff/tool.pyright configs), so the vulnerable code path is reachable.
Published vulnerability details
- Advisory GHSA-p423-j2cm-9vmq (CVE-2026-39892) reports a buffer overflow when a non-contiguous buffer is passed to APIs such as Hash.update() on CPython ≥3.11.
- Impact: crafted inputs can crash the process or trigger memory corruption when hashing or signing data—both of which the platform performs while handling automation credentials.
- Fixed upstream in cryptography 46.0.7.

Impact

A malicious or merely unexpected non-contiguous buffer (e.g. slicing with [::-1]) could be introduced by user-provided automation recipes, remote plan artifacts, or future integrations that proxy binary data through cryptography’s hashing/signature helpers.
Exploitation on Python 3.13 can corrupt memory, leading to denial-of-service or, in worst cases, sandbox escape from security-sensitive agent processes. This violates the Test Infrastructure requirement that delivered builds remain production-safe for milestones v3.2.0–v3.7.0.

Recommendations

Run uv lock --upgrade cryptography (or equivalent) to move the lockfile to cryptography ≥46.0.7.
If necessary, add an explicit top-level dependency override (cryptography>=46.0.7) in pyproject.toml to guarantee the patched floor even when transitive providers lag.
Commit the updated uv.lock and any related metadata.
Re-run required quality gates via nox: nox -s unit_tests, integration_tests, coverage_report, lint, and typecheck to confirm the upgrade keeps tests ≥97% coverage and CI parity.

Acceptance Criteria

uv.lock (and any other lock/constraint artifact) references cryptography 46.0.7 or newer.
Optional dependency overrides ensure downstream packages cannot downgrade below 46.0.7.
All mandated nox sessions pass after the upgrade, with coverage ≥97% and 32-way parallel execution retained.
CI documentation or release notes updated if additional mitigations are required.

## Summary - `uv.lock` currently pins `cryptography==46.0.6`, which is affected by [CVE-2026-39892 / GHSA-p423-j2cm-9vmq](https://github.com/pyca/cryptography/security/advisories/GHSA-p423-j2cm-9vmq). - The vulnerable release enters the runtime via transitive dependencies (`google-auth` and `pyjwt[crypto]`) used by the CleverAgents CLI, so every CLI invocation on Python 3.13 loads the flawed wheel. - Upgrade `cryptography` to the patched 46.0.7+ release and regenerate `uv.lock`, then re-run the mandated nox suites to preserve the 97% coverage threshold and CI parity. ## Findings 1. **cryptography 46.0.6 present in lockfile** - `uv.lock` excerpt: `name = "cryptography"` / `version = "46.0.6"` (pulled via `google-auth` and `pyjwt`). - Python 3.13 is our target interpreter (`pyproject.toml` and `tool.ruff`/`tool.pyright` configs), so the vulnerable code path is reachable. 2. **Published vulnerability details** - Advisory GHSA-p423-j2cm-9vmq (CVE-2026-39892) reports a buffer overflow when a non-contiguous buffer is passed to APIs such as `Hash.update()` on CPython ≥3.11. - Impact: crafted inputs can crash the process or trigger memory corruption when hashing or signing data—both of which the platform performs while handling automation credentials. - Fixed upstream in cryptography 46.0.7. ## Impact - A malicious or merely unexpected non-contiguous buffer (e.g. slicing with `[::-1]`) could be introduced by user-provided automation recipes, remote plan artifacts, or future integrations that proxy binary data through cryptography’s hashing/signature helpers. - Exploitation on Python 3.13 can corrupt memory, leading to denial-of-service or, in worst cases, sandbox escape from security-sensitive agent processes.

Triage Decision [AUTO-OWNR]

Status: ✅ Verified

Type: Task
Priority: Critical
MoSCoW: Must Have
Milestone: Unassigned (Security Infrastructure)

Rationale: CVE-2026-39892 in the cryptography dependency is a security vulnerability that must be patched immediately. Security CVEs are Priority/Critical and Must Have — shipping with known CVEs is not acceptable for production-ready milestones. Immediate attention required.
