CVE-2026-65611 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest nnn.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nnn package and not the nnn package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
nnn does not sanitize the path variable. An attacker can create a directory on a shared filesystem, removable media, or inside an extracted archive whose name contains a single quote followed by shell syntax. If the victim enters that directory in nnn and uses the batch copy or move workflow, the crafted directory name is embedded into the generated shell command and the injected payload executes with the privileges of the nnn process.
