CVE-2026-113720 virtualenv: Seeded files retain permissions from an older cache

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the app-data copy seeder uses shutil.copy to copy cached package files into later environments, causing cached source modes to override the current run's umask. A cache populated under a permissive umask can...
