modules — security advisory
A flaw was found in environment-modules. A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability.
