CVE-2026-50162

CVE-2026-50162 affects the oras-go library. Before 2.6.1, resolveWritePath() in content/file/file.go uses a lexical filepath.Rel check against the workingDir and does not account for symlink traversal, allowing an attacker-controlled blob title (e.g., via ocispec.AnnotationTitle like out/pwn.txt)...

CVE-2026-50163 oras-go: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution in `oras-go` tar extraction

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", "/payload.tar.gz/evilcwdlink" to resolve header.Linkname...

CVE-2026-50163

The CVE concerns the oras-go library (OCI artifacts) prior to version 2.6.2, where ensureLinkPath in content/file/utils.go can return an unresolved hardlink target. During tar extraction, a hardlink entry with a relative Linkname could be resolved against the process CWD, allowing a path like pay...
