CVE-2026-6842
LOWNano: nano: local attacker can inject malicious .desktop launcher due to insecure directory permissions
Title source: cnaDescription
A flaw was found in nano. In environments with permissive umask settings, a local attacker can exploit incorrect directory permissions (0777 instead of 0700) for the `~/.local` directory. This allows the attacker to inject a malicious `.desktop` launcher, which could lead to unintended actions or information disclosure if the launcher is subsequently processed.
