Summary

This PR extends the contribution from ohadmata (thank you! 🙏), cherry-picked from #1067 so the original commit authorship is preserved. Requested by Aaron ("AJ") Steers (@aaronsteers).

The contributor commits widen the snowflake-connector-python bound from >=3.12.2,<4.0 to >=3.12.2,<5.0. My follow-up commit re-locks, because the contributor's lock update only synced the specifier text and still resolved 3.18.0 — so the original PR had no actual security effect.

Exact resolved versions in uv.lock

Package main This PR
snowflake-connector-python 3.18.0 4.7.2
cryptography 44.0.3 46.0.7
pyopenssl 25.1.0 26.2.0
cffi 1.17.1 2.1.1

snowflake-sqlalchemy stays at 1.8.2, which already declares snowflake-connector-python<5.0.0, so the wider bound does not conflict with our other Snowflake dependency.

Why the connector bump is required for the security fix

snowflake-connector-python 3.18.0 pins cffi<2.0.0 and pyOpenSSL<26.0.0, and every cryptography>=46.0.5 requires cffi>=2.0.0. On main, uv lock --upgrade-package cryptography --upgrade-package pyopenssl therefore tops out at cryptography 46.0.0 / pyopenssl 25.3.0 — both below the fixed versions. 4.7.2 requires cryptography>=46.0.5 and drops the cffi and pyOpenSSL caps.

Advisories cleared by the new resolution (OSV, base lock vs. this lock):

Not resolved here: GHSA-537c-gmf6-5ccf (vulnerable OpenSSL in cryptography wheels, fixed in 48.0.1) and CVE-2026-69247/69248/69249 (fixed in 49.0.0–50.0.0) are out of reach of our own cryptography>=44.0.0,!=45.0.0,!=45.0.1,<47.0.0 cap, not of Snowflake's bounds. Widening that cap is a separate decision.

Verification

  • Local: ruff format --check, ruff check, pyrefly check (this repo uses Pyrefly, not MyPy), 489 unit tests — all clean against 4.7.2.
  • Credential-requiring Snowflake tests pass against 4.7.2 in the Ubuntu CI matrix: test_faker_read[Snowflake], test_replace_strategy[Snowflake], test_merge_strategy[Snowflake], test_auto_add_columns[Snowflake], test_cache_create_source_tables[Snowflake], test_sync_to_snowflake[uv_enabled|uv_disabled].

…o 4.7.2

Widening the specifier alone left the lock pinned at 3.18.0, so nothing
actually moved off the old cryptography/OpenSSL builds.

Pull request overview

This PR widens PyAirbyte’s snowflake-connector-python dependency constraint to allow the 4.x series (up to <5.0) and refreshes the uv.lock resolution accordingly, enabling newer Snowflake connector releases and their updated transitive dependency set.

Changes:

  • Updated snowflake-connector-python version constraint from <4.0 to <5.0 in pyproject.toml.
  • Updated uv.lock to reflect the new allowed Snowflake connector version (now resolving snowflake-connector-python 4.7.2) and associated transitive upgrades (notably cryptography, pyopenssl, and cffi).

Reviewed changes

Copilot reviewed 1 out of 2 changed files in this pull request and generated no comments.

File Description
pyproject.toml Expands the allowed Snowflake connector range to include 4.x (<5.0).
uv.lock Updates the resolved dependency set for the widened connector range (including the Snowflake connector and related crypto stack packages).

Devin, the body of the PR should name exactly how to version resolved in the updated lock file

Done — the body now names the exact resolved versions: snowflake-connector-python 3.18.0 → 4.7.2, cryptography 44.0.3 → 46.0.7, pyopenssl 25.1.0 → 26.2.0, cffi 1.17.1 → 2.1.1, with snowflake-sqlalchemy unchanged at 1.8.2.
