CVE-2020-26279 Information

Description

go-ipfs is an open-source golang implementation of IPFS which is a global versioned peer-to-peer filesystem. In go-ipfs before version 0.8.0-rc1 it is 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 a get is done on an affected DAG. This is fixed in version 0.8.0-rc1.
