What is CVE-2026-85013?

A vulnerability in the environment-modules package allows local attackers to execute arbitrary commands by placing a carefully crafted module file in a directory within the victim's MODULEPATH. When a user employs Bash completion for module or ml commands, the maliciously named module is treated as a command due to the inclusion of shell metacharacters, potentially compromising the user's confidentiality, integrity, and availability. This flaw could have significant implications depending on the privileges of the victim.
