CVE-2021-21372 is a critical vulnerability affecting Nimble, the package manager for the Nim programming language, in versions prior to 1.2.10 and 1.4.4. This flaw allows for arbitrary command execution due to improper handling of the doCmd function, which can be triggered by a specially crafted entry in the packages.json package list. With a CVSS score of 8.8 (High), it presents a significant risk, as an unauthenticated attacker can achieve high impact on confidentiality, integrity, and availability with low attack complexity, requiring user interaction. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
