Description Vipul Nair 2026-10-21 12:53:30 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

uv is a Python package and project manager written in Rust. From 0.12.7 until 0.12.18, uv wheel extraction on Windows can process a malicious wheel in a way that writes a file outside the installation prefix, including an executable in a directory already present on the user's PATH. Non-Windows hosts are not affected. This issue is fixed in version 0.12.18.

Comment 1 Ben Beasley 2026-10-21 14:21:10 UTC
Fortunately, Fedora isn’t Windows.

Comment 2 Miro Hrončok 2026-10-21 14:23:16 UTC
Also, we are on 0.12.19+
