oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link("victim.secret", "<extract_base>/payload.tar.gz/evil_cwd_link") to resolve header.Linkname against the process current working directory for a Typeflag=TypeLink entry such as Name=payload.tar.gz/evil_cwd_link and Linkname="victim.secret" with io.deis.oras.content.unpack: "true", which can expose or tamper with files such as .env, .git/config, .aws/credentials, and ~/.ssh/config. This issue is fixed in version 2.6.2.
