A flaw was found in oras-go. The file content store, intended to confine writes to a specified working directory, does not properly account for symbolic link (symlink) traversal. A remote attacker, by providing a specially crafted blob title, could exploit this vulnerability to create files outside the intended working directory. This filesystem boundary bypass allows for arbitrary file creation, potentially leading to unauthorized data modification or system compromise depending on the runtime environment.
