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 information disclosure if the launcher is subsequently processed.
What this means for your business
- An attacker can use it only with access to the machine itself, with an ordinary user login, and without anyone at your company clicking anything.
- FIRST's prediction model gives it a less than 0.1% chance of attack attempts being seen in the next 30 days, ranking above 0% of all known flaws.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
