GHSA-M37J-52J7-PJW7 oras-go: Arbitrary file write outside file.Store root via symlink-chain bypass in tar extraction (pushDir)

Summary The content/file.Store in oras-go v2 unpacks OCI layer tarballs when a descriptor carries io.deis.oras.content.unpack=true. The extraction routine validates symlink targets purely lexically filepath.Join and, for regular files placed directly at the extraction root, skips the parent-symli...

CVE-2026-85731 oras-go: Arbitrary file write outside file.Store root via symlink-chain bypass in tar extraction (pushDir)

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...

CVE-2026-85731

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2 , the content/file.Store extraction of OCI layers marked with io.deis.oras.content.unpack=true is vulnerable to an arbitrary file-write outside the store's working directory. The root cause lies in the pushDir path: extractTarDire...
