CVE-2026-50162 Details
Description
oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, resolveWritePath() in content/file/file.go uses a lexical filepath.Rel check for workingDir and does not account for symlink traversal, so when AllowPathTraversalOnWrite=false an attacker-controlled blob title through ocispec.AnnotationTitle such as out/pwn.txt can follow a workingDir symlink out -> /some/outside/dir and cause pushFile() to create /some/outside/dir/pwn.txt outside workingDir. This issue is fixed in version 2.6.1.
A vulnerability in the Oras-Go library prior to version 2.6.1 allows for directory traversal via symlinks, causing files to be written outside the designated working directory. This occurs when 'AllowPathTraversalOnWrite' is set to false, and an attacker-controlled blob title targets a path under a symlink that points to an external directory. The issue arises because the library's lexical checks do not account for symlink resolution, allowing writes to escape the intended boundaries.
Users can update to Oras-Go version 2.6.1 or later, where this vulnerability has been fixed.
