  "title": "nano: A flaw was found in nano",
  "description": "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 \u0060~/.local\u0060 directory. This allows the attacker to inject a malicious \u0060.desktop\u0060 launcher, which could lead to unintended actions or information disclosure if the launcher is subsequently processed.",
