The file content store in `oras-go` attempts to confine writes to `workingDir` when `AllowPathTraversalOnWrite=false`, but the guard is lexical and does not account for symlink traversal. If `workingDir` contains a symlink path component and an attacker-controlled blob title (via `ocispec.AnnotationTitle`) targets a path under that symlink, `pushFile()` can create a file outside `workingDir`. ## relevant links - repository: https://github.com/oras-project/oras-go - commit: 03243809936cce826494
