CVE-2021-42343 describes a critical remote code execution vulnerability in the Dask distributed package before version 2021.10.0, specifically affecting single-machine Dask clusters created with LocalCluster or Client. These clusters would incorrectly bind Dask workers to external interfaces instead of localhost, making them accessible. With a CVSS score of 9.8 (Critical), this vulnerability allows unauthenticated attackers to achieve full compromise (confidentiality, integrity, availability) with low attack complexity over the network. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
