Summary
Fluxion before 6.39 contains an OS command injection vulnerability in the fluxion.sh target scanner, which decodes access point ESSIDs with eval after escaping only single quotes. Attackers within Wi-Fi range can broadcast an access point with a crafted SSID to execute commands as root when the operator scans or selects it.

Questions about CVE-2026-125399
Is CVE-2026-125399 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
A crafted Wi-Fi network name (SSID) can make Fluxion run arbitrary shell commands as root on the operator's machine when the operator scans for networks or selects that access point as a target.Source: vulncheck.com
Which versions are affected by CVE-2026-125399?
fluxion: before 6.39.Source: cve.now feed data
Am I affected, and how do I check?
All Fluxion versions before 6.39 are affected. To check, look at the Fluxion version shown when it starts or in its release files; a version lower than 6.39 falls in the affected range.Source: vulncheck.com
How do I fix CVE-2026-125399?
