Dynamic languages vulnerable to module import exploits, authors find

This article explores a security vulnerability where malicious code can be injected into software by exploiting how dynamic languages resolve module imports. By placing a specially crafted file in a directory that is part of the runtime's module search path, an attacker can trick the system into executing their code instead of the intended library. The author details how various languages like Python, Ruby, Perl, Node.js, Java, and Julia have handled or mitigated this issue, with some removing the current directory from default search paths and others implementing stricter import mechanisms.
