CVE-2026-40556

In the connected Debian/CVE entry, GNU nano is affected by a local permission issue: when the user’s ~/.local directory does not exist, nano creates it with mode 0777, making it world‑writable in environments where the umask is lax. This creates a race window where an attacker could leverage the ...

GNU nano creates the user’s /.local directory with overly permissive permissions when the directory does not exist yet. On first use of features requiring Cross-Desktop Group XDG data storage, nano explicitly requests directory mode 0777, making the directory world‑writable in environments where...

CVE-2026-6842

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...
