Questions about CVE-2026-120197
What does this mean?
The web management interface passes the name parameter of the port forwarding function to the system shell without proper filtering. A logged-in user can therefore add their own shell commands, which run with the privileges of the web service and could lead to full control of the device.Source: github.com
Am I affected, and how do I check?
The listed condition is the WAVLINK WL-WN530HG4B router with firmware M_V260724. To compare, check the firmware version shown in the router's web admin interface against that value.Source: github.com
What should I do about it?
The checked facts name no fixed firmware version, so there is no upgrade target to recommend. Check WAVLINK's support site for a newer firmware release and apply it when one is available.Source: github.com
Is it 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 if there's no patch?
The checked facts give no workaround. Because the flaw needs an authenticated session, limit who can log in to the router's web interface, change the admin password to a strong unique one, and keep the interface off untrusted networks.Source: github.com
