CVE-2026-113714: virtualenv: Downloaded wheel selection and caching precede verification

October 23, 2026

Wheel downloads go directly into the reusable wheelhouse, while the verification target is selected from pip’s textual output. A verification failure does not remove the downloaded file from that cache.

Anthropic’s OSS Scanner reported this as ANT-2026-ST00DRO3 in virtualenv-20261015-005, received on 15 October 2026.
