chore(deps): bump cryptography from 46.0.5 to 50.0.0 in /envs/sumo_rl_env

[dependabot]

Bumps cryptography from 46.0.5 to 50.0.0.

Changelog

Sourced from cryptography's changelog.

50.0.0 - 2026-07-31

* **SECURITY ISSUE**:
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der`
  and its PEM and S/MIME variants no longer expose distinguishable errors or
  timing when unwrapping a ``RecipientInfo``'s ``encryptedKey``, which could
  act as a Bleichenbacher oracle for callers that decrypt untrusted messages.
  A random key is now substituted on failure, as described in :rfc:`3218`.
  Credit to **@X1AOxiang** for reporting the issue. **CVE-2026-69247**
* Deprecated Diffie-Hellman key exchange over finite fields (FFDH).
  Everything FFDH is deprecated, including the types in
  ``cryptography.hazmat.primitives.asymmetric.dh`` and loading FFDH keys or
  parameters with the key loading APIs. Users should migrate to a more
  modern key exchange algorithm.
* Added ``xof()`` class methods to
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE128` and
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE256` for constructing
  algorithm instances configured for use with
  :class:`~cryptography.hazmat.primitives.hashes.XOFHash`.
* The :mod:`X.509 verification <cryptography.x509.verification>` APIs are now
  considered stable and are subject to our API stability policy.
* Added the :doc:`/cobblestone` recipe, an implementation of the
  Cobblestone-128 and Cobblestone-256 instantiations of the `C2SP
  chunked-encryption specification
  <https://c2sp.org/chunked-encryption>`_ for streaming authenticated
  encryption of large messages.
* Parsing a Signed Certificate Timestamp list now rejects encodings that
  carry trailing bytes after the list or after an individual SCT, instead of
  silently ignoring them.
* Added support for using :class:`~cryptography.x509.Name` as a field type in
  the :doc:`/hazmat/asn1/index` module.
* Loading a public key or an EC private key now rejects DER where the
  ``subjectPublicKey`` (or EC ``publicKey``) ``BIT STRING`` declares a non-zero
  number of unused bits, instead of silently ignoring it.
* Parsing a CRL entry's ``InvalidityDate`` extension now rejects a
  ``GeneralizedTime`` that carries fractional seconds or another non-DER form,
  matching the strict encoding already required for every other X.509 time
  field.
* :func:`~cryptography.x509.ocsp.load_der_ocsp_request` and
  :func:`~cryptography.x509.ocsp.load_der_ocsp_response` now reject a request
  or response whose ``version`` field is not ``v1``, the only version defined
  by RFC 6960, matching the version validation already performed when loading
  certificates, CSRs and CRLs.
* :class:`~cryptography.hazmat.primitives.hashes.XOFHash` is now supported
  when building against AWS-LC.
* HMAC (and therefore PBKDF2-HMAC) with SHA-3 hashes is now supported when
  building against AWS-LC.
* Diffie-Hellman (:doc:`/hazmat/primitives/asymmetric/dh`) is now supported
  when building against AWS-LC.

Note

Medium Risk
Major-version bump of a security-sensitive transitive crypto library (via Authlib/SecretStorage); low direct code impact but worth smoke-testing installs and any auth/keyring paths on target platforms.

Overview
Updates envs/sumo_rl_env/uv.lock so the resolved cryptography package moves from 46.0.5 to 50.0.0, including refreshed sdist/wheel URLs and hashes for the new release.

The lock refresh also simplifies a few transitive dependency markers (e.g. pandas and secretstorage entries) as part of re-resolution; there are no application or pyproject source changes in this PR.

Alignment Review Report

Automated two-tier review of the cryptography 46.0.5 → 50.0.0 transitive lock bump in envs/sumo_rl_env.

Automated Checks

• Lint: PASS (for this PR). bash .claude/hooks/lint.sh exits 1, but only on the ~20 pre-existing unformatted envs/** files (agent_world_model_env, chat_env, opencode_env, …). sumo_rl_env is not among them (0 matches), and this PR touches only uv.lock, which is not linted. The meaningful check for a lock bump — uv lock --check --project envs/sumo_rl_env — passes (126 packages resolved).
• Debug code: CLEAN. check-debug.sh scans src/ only; every hit is a pre-existing docstring print() / TODO. This PR touches only envs/sumo_rl_env/uv.lock.

Open RFCs Context

RFCs on main: 000–005 + 010 (In Review / Draft). None govern dependency management, PyPI indexes, or packaging, so a transitive security bump has no RFC surface. Runtime-API / rewards-in-env / client-server / MCP / credential invariants are likewise untouched.

Tier 1: Fixes Required

None. Verification of the bump:

• Transitive → lock-only is correct. cryptography is not in pyproject.toml; it's pulled via authlib 1.6.12, pyjwt[crypto], and secretstorage 3.5.0 (the openenv → fastmcp → keyring chain). No pyproject / requires-dist edit is expected, and none is present.
• Hashes verified against PyPI. sdist sha256:eeac2acb…a6c9 (880201 B) plus spot-checked wheels (cp311 / cp39 / pp311 / cp314) match pypi.org/pypi/cryptography/50.0.0/json sha256 + size exactly; none yanked. requires_python !=3.9.0,!=3.9.1,>=3.9 is satisfied by the env's >=3.10.
• Born-clean lock. revision = 3 and 0 HF-mirror refs at both base and head (143 pypi.org/simple on each side); no files.pythonhosted.org line changed outside cryptography-*. So none of the usual re-lock side effects (index-flip / revision bump / requires-dist re-sync) apply here.
• Security-positive. The 46 → 50 jump clears the 11 advisories carried by 46.0.5 (GHSA-g6cj-pr64-35w5 / CVE-2026-69247 is fixed in exactly 50.0.0, plus 10 earlier fixes); PyPI lists 0 vulnerabilities for 50.0.0. This justifies the large version jump.
• Incidental benign marker normalizations (not a regression): the re-resolve also simplified redundant environment markers on pandas 2.3.3 / 3.0.1 inner deps (numpy / python-dateutil / pytz / tzdata) and on secretstorage (cryptography / jeepney). These are semantically equivalent within each entry's resolution-markers scope — pandas / numpy resolved versions are unchanged, and keyring still gates secretstorage to sys_platform == 'linux'. uv lock --check passing confirms overall consistency.

Tier 2: Alignment Discussion

Principle Conflicts

None identified. A transitive security patch touches no principle/invariant surface (Gym API, rewards-in-environment, client-server separation, MCP boundary, credential handling).

RFC Conflicts

None identified.

ALIGNMENT FLAG (process, non-blocking): native dependabot PR bypasses exclude-paths

• Policy at stake: .github/dependabot.yml — the uv updater declares directory: "/" with exclude-paths: ["envs/**"] (commit 5f499da, #566).
• The concern: this native dependabot/uv/envs/sumo_rl_env/cryptography-50.0.0 PR edits envs/sumo_rl_env/uv.lock, exactly the path exclude-paths: ["envs/**"] is meant to exclude. exclude-paths is valid config, but the uv ecosystem isn't honoring it (platform limitation); the intended channel for env bumps is the codex/dependabot-envs-* aggregate roll-ups. The change itself is correct and worth landing — this is only a note that the env-scope exclusion isn't taking effect. No action needed on this PR.
• Suggested reviewer: @burtenshaw (author of the exclude-paths lines / dependabot config)

Summary

• 0 mechanical issues to fix
• 1 alignment point for human review (dependabot exclude-paths process note, non-blocking)
• 0 RFC conflicts

Net: a clean, born-clean, security-positive transitive bump — safe to merge on its own merits.

cryptography 46.0.5 → 50.0.0 (transitive via authlib / pyjwt[crypto] / secretstorage).

Verified: sdist sha256:eeac2acb…a6c9 + spot-checked wheels (cp311/cp39/pp311/cp314) match PyPI exactly (none yanked); requires_python !=3.9.0,!=3.9.1,>=3.9 ⊇ env >=3.10; uv lock --check passes (126 pkgs).

Security-positive — clears the 11 advisories on 46.0.5 (incl. CVE-2026-69247, fixed in exactly 50.0.0); 0 vulns on 50.0.0.

Lock is born-clean (rev 3, all pypi.org/simple at base + head), so no index-flip / revision side effects.

Closing in favor of aggregate env Dependabot PR #1015.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
