Changelog

Sourced from cryptography's changelog.

46.0.7 - 2026-04-07

* **SECURITY ISSUE**: Fixed an issue where non-contiguous buffers could be
  passed to APIs that accept Python buffers, which could lead to buffer
  overflow. **CVE-2026-39892**
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.5.6.
.. _v46-0-6:
46.0.6 - 2026-03-25

• SECURITY ISSUE: Fixed a bug where name constraints were not applied to peer names during verification when the leaf certificate contains a wildcard DNS SAN. Ordinary X.509 topologies are not affected by this bug, including those used by the Web PKI. Credit to Oleh Konko (1seal) for reporting the issue. CVE-2026-34073

.. _v46-0-5:

46.0.5 - 2026-02-10

* An attacker could create a malicious public key that reveals portions of your
  private key when using certain uncommon elliptic curves (binary curves).
  This version now includes additional security checks to prevent this attack.
  This issue only affects binary elliptic curves, which are rarely used in
  real-world applications. Credit to **XlabAI Team of Tencent Xuanwu Lab and
  Atuin Automated Vulnerability Discovery Engine** for reporting the issue.
  **CVE-2026-26007**
* Support for ``SECT*`` binary elliptic curves is deprecated and will be
  removed in the next release.
.. v46-0-4:
46.0.4 - 2026-01-27

• Dropped support for win_arm64 wheels_.
• Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.5.5.

.. _v46-0-3:

46.0.3 - 2025-10-15

* Fixed compilation when using LibreSSL 4.2.0.

Updates flask from 2.2.5 to 3.1.3

Release notes

Sourced from flask's releases.

3.1.3

This is the Flask 3.1.3 security fix release, which fixes a security issue but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.3/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-3

• The session is marked as accessed for operations that only access the keys but not the values, such as in and len. GHSA-68rp-wp8r-4726

3.1.2

This is the Flask 3.1.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.2/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-2 Milestone: https://github.com/pallets/flask/milestone/38?closed=1

• stream_with_context does not fail inside async views. #5774
• When using follow_redirects in the test client, the final state of session is correct. #5786
• Relax type hint for passing bytes IO to send_file. #5776

3.1.1

This is the Flask 3.1.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.1/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-1 Milestone https://github.com/pallets/flask/milestone/36?closed=1

• Fix signing key selection order when key rotation is enabled via SECRET_KEY_FALLBACKS. GHSA-4grg-w6v8-c28g
• Fix type hint for cli_runner.invoke. #5645
• flask --help loads the app and plugins first to make sure all commands are shown. #5673
• Mark sans-io base class as being able to handle views that return AsyncIterable. This is not accurate for Flask, but makes typing easier for Quart. #5659

3.1.0

This is the Flask 3.1.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecations, or introduce potentially breaking changes. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

PyPI: https://pypi.org/project/Flask/3.1.0/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-0 Milestone: https://github.com/pallets/flask/milestone/33?closed=1

• Drop support for Python 3.8. #5623
• Update minimum dependency versions to latest feature releases. Werkzeug >= 3.1, ItsDangerous >= 2.2, Blinker >= 1.9. #5624, #5633
• Provide a configuration option to control automatic option responses. #5496
• Flask.open_resource/open_instance_resource and Blueprint.open_resource take an encoding parameter to use when opening in text mode. It defaults to utf-8. #5504
• Request.max_content_length can be customized per-request instead of only through the MAX_CONTENT_LENGTH config. Added MAX_FORM_MEMORY_SIZE and MAX_FORM_PARTS config. Added documentation about resource limits to the security page. #5625
• Add support for the Partitioned cookie attribute (CHIPS), with the SESSION_COOKIE_PARTITIONED config. #5472
• -e path takes precedence over default .env and .flaskenv files. load_dotenv loads default files in addition to a path unless load_defaults=False is passed. #5628
• Support key rotation with the SECRET_KEY_FALLBACKS config, a list of old secret keys that can still be used for unsigning. Extensions will need to add support. #5621
• Fix how setting host_matching=True or subdomain_matching=False interacts with SERVER_NAME. Setting SERVER_NAME no longer restricts requests to only that domain. #5553
• Request.trusted_hosts is checked during routing, and can be set through the TRUSTED_HOSTS config. #5636

Bugs fixed

• LP#2107279: Binary wheels use libxml2 2.13.8 and libxslt 1.1.43 to resolve several CVEs. (Binary wheels for Windows continue to use a patched libxml2 2.11.9 and libxslt 1.1.39.) Issue found by Anatoly Katyushin, see https://bugs.launchpad.net/lxml/+bug/2107279

Changelog

Sourced from lxml's changelog.

6.1.0 (2026-04-17)

This release fixes a possible external entity injection (XXE) vulnerability in iterparse() and the ETCompatXMLParser.

Features added

• GH#486: The HTML ARIA accessibility attributes were added to the set of safe attributes in lxml.html.defs. This allows lxml_html_clean to pass them through. Patch by oomsveta.

• The default chunk size for reading from file-likes in iterparse() is now configurable with a new chunk_size argument.

Bugs fixed

• LP#2146291: The resolve_entities option was still set to True for iterparse and ETCompatXMLParser, allowing for external entity injection (XXE) when using these parsers without setting this option explicitly. The default was now changed to 'internal' only (as for the normal XML and HTML parsers since lxml 5.0). Issue found by Sihao Qiu as CVE-2026-41066.

6.0.4 (2026-04-12)

Bugs fixed

• LP#2148019: Spurious MemoryError during namespace cleanup.

6.0.3 (2026-04-09)

Bugs fixed

• Several out of memory error cases now raise MemoryError that were not handled before.

• Slicing with large step values (outside of +/- sys.maxsize) could trigger undefined C behaviour.

• LP#2125399: Some failing tests were fixed or disabled in PyPy.

• LP#2138421: Memory leak in error cases when setting the public_id or system_url of a document.

Updates pyopenssl from 24.3.0 to 26.0.0

Changelog

Sourced from pyopenssl's changelog.

26.0.0 (2026-03-15)

Backward-incompatible changes: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

• Dropped support for Python 3.7.
• The minimum cryptography version is now 46.0.0.

Deprecations: ^^^^^^^^^^^^^

Changes: ^^^^^^^^

• Added support for using aws-lc instead of OpenSSL.
• Properly raise an error if a DTLS cookie callback returned a cookie longer than DTLS1_COOKIE_LENGTH bytes. Previously this would result in a buffer-overflow. Credit to dark_haxor for reporting the issue. CVE-2026-27459
• Added OpenSSL.SSL.Connection.get_group_name to determine which group name was negotiated.
• Context.set_tlsext_servername_callback now handles exceptions raised in the callback by calling sys.excepthook and returning a fatal TLS alert. Previously, exceptions were silently swallowed and the handshake would proceed as if the callback had succeeded. Credit to Leury Castillo for reporting this issue. CVE-2026-27448

25.3.0 (2025-09-16)

Backward-incompatible changes: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Deprecations: ^^^^^^^^^^^^^

Deprecations: ^^^^^^^^^^^^^

Changes: ^^^^^^^^

• pyOpenSSL now sets SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER on connections by default, matching CPython's behavior.
