CVE-2026-121549

nnn through 5.3 contains an insecure temporary file vulnerability in the pdfread and nuke plugins that allows local attackers to overwrite files by exploiting predictable paths in /tmp. Attackers can pre-create a symlink at the name-derived or PID-derived path so the victim's plugin truncates and overwrites any file the victim can write.
