fix: flatten path separators in pack output filename#9468
Merged
Conversation
`npm pack` writes the tarball to a name built from `manifest.name` with a non-global `.replace(/\//, '-')`, which only strips the single scope slash. When packing a remote tarball, git, or directory spec the name comes from a package.json that the registry never validated, so a name like `x/../../../escaped` keeps its `../` segments and `path.resolve(packDestination, filename)` lands the tarball outside the destination. Make the separator replacement global so the filename is always one path component. (cherry picked from commit 76f8059)
