There is no fixed version for Debian:10 nim.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nim package and not the nim package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS without full verification of the SSL/TLS certificate due to the default setting of httpClient. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution.
