Description
A flaw was found in oras-go, a Go library used for managing OCI (Open Container Initiative) artifacts. An attacker can exploit this vulnerability by providing a specially crafted tarball containing a malicious hardlink. When this tarball is extracted, the hardlink can be manipulated to point to files outside the intended extraction location, specifically within the victim's current working directory. This allows an attacker to read sensitive information from the system, and in some cases, could lead to unauthorized access to critical system files if the component is operating with elevated privileges.
