CVE-2021-25327
Skyworth Digital Technology RN510 V.3.1.0.4 contains a cross-site request forgery (CSRF) vulnerability in /cgi-bin/net-routeadd.asp and /cgi-bin/sec-urlfilter.asp.
Does this matter?
Lower severity and a low EPSS score (0.90%). Track it; it rarely justifies an emergency change on its own.
