nnn through 5.3 OS Command Injection via togglex Plugin

Summary

Jarun nnn through 5.3 contains an OS command injection vulnerability in plugins/togglex that allows attackers to execute commands via crafted filenames. Attackers can place files whose names contain a double quote and shell syntax, which xargs -I splices into an sh -c script, running commands as the user invoking togglex.

Remediation

1. Inventory every jarun nnn deployment, including staging.
2. No fixed version appears in the public sources yet. Check the references below and the vendor directly.
