Bugfixes - 21.2.4

• Security hardening: validate each entry of a seed wheel archive before extracting it so a tampered wheel cannot escape the app-data image directory via an absolute path or .. traversal. (:issue:3118)
• Security hardening: verify the SHA-256 of every bundled seed wheel when it is loaded so a corrupted or tampered file on disk fails loud instead of being handed to pip. The hash table is generated alongside BUNDLE_SUPPORT by tasks/upgrade_wheels.py. (:issue:3119)
• Security hardening: validate the distribution name and version specifier passed to pip download when acquiring a seed wheel so extras, pip flags, or shell metacharacters cannot be smuggled into the subprocess command line. (:issue:3120)
• Security hardening: replace the string-prefix containment check in virtualenv.util.zipapp with Path.relative_to so the zipapp extraction helpers refuse any path that does not resolve under the archive root. (:issue:3121)
• Security hardening: do not silently fall back to an unverified HTTPS context when the periodic update request to PyPI fails TLS verification. The returned metadata drives which wheel version virtualenv considers "up to date", so accepting an unverified response lets a network-level attacker suppress security updates. Set VIRTUALENV_PERIODIC_UPDATE_INSECURE=1 to restore the previous behavior on hosts with broken trust stores. (:issue:3122)

Code Review

PR Summary: Bumps virtualenv from 21.2.3 to 21.2.4 in the development dependency group.

---

Code Quality

• ✅ Style guide: Single-line change in pyproject.toml, no style concerns.
• ✅ No commented-out code
• ✅ Meaningful variable names: N/A
• ✅ DRY principle: N/A
• ✅ Defects: No logic changes; this is a patch version bump for a dev-only tool.
• ✅ CLAUDE.md: No issues. The project configuration is appropriately general.

Testing

• ✅ Unit/integration tests: N/A — dependency version bump only; virtualenv is a development tool, not a runtime dependency.
• ✅ Test coverage: No code changed.

Documentation

• ✅ README: No update needed.
• ✅ API docs: N/A
• ✅ Inline comments: N/A
• ✅ CHANGELOG.md: Not updated — acceptable for an automated dependency bump.
• ✅ Markdown formatting: No markdown files changed.

Security

• ✅ No hardcoded credentials
• ✅ No sensitive data
• ✅ No license files (.lic) checked in
• ✅ Dependency scope: virtualenv is scoped to development only — it is not included in production builds, so the risk surface is minimal. Patch bumps of this kind are typically safe (bug fixes only).
