build(deps): bump idna from 3.10 to 3.15 in /integration-tests

[dependabot]

Bumps idna from 3.10 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.

3.13 (2026-04-22)

• Correct classification error for codepoint U+A7F1

3.12 (2026-04-21)

• Update to Unicode 17.0.0.
• Issue a deprecation warning for the transitional argument.
• Added lazy-loading to provide some performance improvements.
• Removed vestiges of code related to Python 2 support, including segmentation of data structures specific to Jython.

Thanks to Rodrigo Nogueira for contributions to this release.

3.11 (2025-10-12)

• Update to Unicode 16.0.0, including significant changes to UTS46 processing. As a result of Unicode ending support for it, transitional processing no longer has an effect and returns the same result.

📋 Executive Summary

This is a Dependabot security bump updating idna from 3.10 to 3.15 in /integration-tests/uv.lock. The update addresses CVE-2026-45409 (ReDoS via crafted inputs), a bypass of the original CVE-2024-3651 fix. This is a transitive dependency (used by anyio → httpx → the integration test suite). The change is minimal: 3 lines in the lock file (version, sdist hash, wheel hash). No breaking changes in the idna 3.10→3.15 upgrade path. Build, CI, and CVE mitigation tests all pass.

🔴 Breaking Changes

✅ No breaking changes detected. The idna 3.10→3.15 changelog confirms:

• 3.10→3.11: Unicode 16.0.0 support, Python 3.14 support. Transitional processing deprecated but still works (returns same result).
• 3.12: Unicode 17.0.0. Lazy-loading added (performance, not API change). Python 2 vestiges removed (irrelevant for Python ≥3.12 target).
• 3.13: Bugfix for codepoint U+A7F1 classification.
• 3.14: CVE-2026-45409 fix — ReDoS mitigated via early length rejection.
• 3.15: Early DNS-length enforcement in check_label. Internal refactors (frozensets, f-strings, error chaining). No public API changes.

⚠️ Issues Found

✅ No issues found. Single-file lockfile change, no code modifications.

🔬 Logical / Bug Analysis

Change analysis:

• File: integration-tests/uv.lock — only the [[package]] name = "idna" section changed
• Old version: 3.10 (2024-09-15)
• New version: 3.15 (2026-05-12)
• sdist hash: 12f65c9b...13ea9 → ca962446...65fdc (verified via uv sync --frozen — hash matches PyPI)
• Wheel hash: 946d195a...1287d3 → 048adeaf...10ac8 (verified)
• No other transitive dependencies shifted

Security significance: CVE-2026-45409 (CVSS 5.1 Medium) is a ReDoS that allows crafted Unicode inputs (U+0660 * N, U+30FB * N + U+6F22) to cause quadratic-time processing in the valid_contexto function. idna 3.14+ rejects oversize inputs before they reach the regex engine. This is a legitimate security fix — no reason to hold it.

👥 Human Review Feedback

No human review comments on this PR. Only two bot comments (hermes-exosphere: "awaiting review" + "review started"), both informational, no action required.

---

💡 Suggestions

• Consider enabling Dependabot auto-merge for patch-level transitive deps — idna is a transitive dependency of httpx/anyio, and this PR is a pure security bump with no code changes. Auto-merge for uv.lock-only dep bumps (with passing CI) would reduce maintainer toil.
• Label this PR with security — currently labeled dependencies and python:uv. Adding a security label would help with audit trails given this addresses a CVE.
