Echo: oras.land/oras-go/v2: security update to 2.6.2-1

high Tenable Self-Hosted Container Security Plugin ID 462602

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, content/file.Store extraction of OCI
 layers marked with io.deis.oras.content.unpack=true can write outside the store working directory. The
 pushDir path through extractTarDirectory and ensureLinkPath validates symlink targets lexically,
 resolveRelToBase skips its parent-symlink walk for root-level entries, and writeFile follows a terminal
 symlink when opening a regular file. A malicious archive can therefore create a symlink chain whose
 lexical target remains inside the extraction root but whose resolved target is an attacker-selected
 absolute path, then overwrite that target with a same-named regular-file entry even when
 AllowPathTraversalOnWrite is false. Pulling an attacker-controlled artifact can create or overwrite any
 file writable by the process and may lead to code execution. This issue is fixed in version 2.6.2.
 (CVE-2026-85731)

Solution

Update the oras.land/oras-go/v2 library and its related packages to version 2.6.2-1 or later.
