Path traversal in github.com/ipfs/go-ipfs
Impact
It is currently possible for path traversal to occur with DAGs containing relative paths during retrieval. This can cause files to be overwritten, or written to incorrect output directories. The issue can only occur when ipfs get
is done on an affected DAG.
- The only affected command is
ipfs get
. - The gateway is not affected.
