Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A path traversal vulnerability exists in the EmailSheet extract_parts functionality of VisiData (version(s): dev (commit 38b21f78)). A specially crafted .eml file can lead to arbitrary file write. An attacker can provide a malicious file to trigger this vulnerability.
