CVE-2026-65611

MEDIUMPre-NVD 5.15.1
EchelonGraph scoreLOW confidence

This medium-severity CVE scores 5.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.

Maintainer of this project was notified about this vulnerability. It might has been addressed, but the maintainer did not provide a vulnerable version range. Only version 5.2 was tested and confirmed as vulnerable.
