Bumps uv from 0.8.22 to 0.9.5.

Release notes

Sourced from uv's releases.

0.9.5

Release Notes

Released on 2025-10-21.

This release contains an upgrade to astral-tokio-tar, which addresses a vulnerability in tar extraction on malformed archives with mismatching size information between the ustar header and PAX extensions. While the astral-tokio-tar advisory has been graded as "high" due its potential broader impact, the specific impact to uv is low due to a lack of novel attacker capability. Specifically, uv only processes tar archives from source distributions, which already possess the capability for full arbitrary code execution by design, meaning that an attacker gains no additional capabilities through astral-tokio-tar.

Regardless, we take the hypothetical risk of parser differentials very seriously. Out of an abundance of caution, we have assigned this upgrade an advisory: GHSA-w476-p2h3-79g9

Security

  • Upgrade astral-tokio-tar to 0.5.6 to address a parsing differential (#16387)

Enhancements

  • Add required environment marker example to hint (#16244)
  • Fix typo in MissingTopLevel warning (#16351)
  • Improve 403 Forbidden error message to indicate package may not exist (#16353)
  • Add a hint on uv pip install failure if the --system flag is used to select an externally managed interpreter (#16318)

Bug fixes

  • Fix backtick escaping for PowerShell (#16307)

Documentation

  • Document metadata consistency expectation (#15683)
  • Remove outdated aarch64 musl note (#16385)
