Comment 1 Ben Beasley 2026-03-20 10:12:35 UTC
See https://www.cve.org/CVERecord?id=CVE-2026-32766. This is fixed in astral-tokio-tar 0.6.0, https://src.fedoraproject.org/rpms/rust-astral-tokio-tar/pull-request/3, which must be shipped together with uv 0.10.12 (released yesterday). I expect to be able to make updates for stable branches within the next few days, possibly as soon as today.
