Updates bleach from 6.3.0 to 6.4.0

Changelog

Sourced from bleach's changelog.

Version 6.4.0 (June 5th, 2026)

NOTE: 2026-06-05: Bleach is no longer maintained. There will be no future releases including for security issues. See issue: <https://github.com/mozilla/bleach/issues/698>__

Backwards incompatible changes

  • Dropped support for pypy 3.10. (#764)

Security fixes

  • Fix bug 2023812 / GHSA-8rfp-98v4-mmr6.

    Fix XSS issue with sanitize_uri_value where disallowed schemes with Unicode invisible characters wouldn't be rejected.

    For example::

    import bleach payload1 = 'Click' result1 = bleach.clean(payload1) print(repr(result1))

    outputs::

    'Click'

    See the advisory for details.

  • Fix GHSA-gj48-438w-jh9v.

    Fix issue where URI sanitization wasn't happening in formaction attributes.

    See the advisory for details.

Bug fixes

  • Add support for pypy 3.11. (#764)

  • Drop version max in tinycss2 pin. (#772)

    This removes one of the things we had to keep checking and updating. Users now own the responsibility for correctness with the version of tinycss2 they're using.

Updates idna from 3.13 to 3.15

Changelog

Sourced from idna's changelog.

3.15 (2026-05-12)

  • Enforce DNS-length cap on individual labels early in check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.
  • Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared _unicode_dots_re from idna.core in the codec module.
  • Use raise ... from err for proper exception chaining and switch internal string formatting to f-strings.
  • Allow flit_core 4.x in the build backend.
  • Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
  • Add Dependabot configuration for GitHub Actions.
  • Convert README and HISTORY from reStructuredText to Markdown.
  • Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.

Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

3.14 (2026-05-10)

  • Removed opportunity to process long inputs into quadratic time by rejecting oversize inputs up-front. Closes a bypass of the CVE-2024-3651 mitigation. [CVE-2026-45409]

Thanks to Stan Ulbrych for reporting the issue.
