CVE-2026-6842
LowCVSS 2.5Exploitation Probability (EPSS)
Low risk0th percentile - higher than 0% of all known CVEs
Summary
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.
Risk Assessment
A local attacker could gain access to user data or cause unintended actions, compromising confidentiality and integrity of the user environment.
Recommendation
Update nano to a patched version. Additionally, check and correct permissions of the `~/.local` directory to 0700.
