Cross-site scripting vulnerability in the management screen of Cybozu Remote Service 3.0.0 to 3.1.9 allows a remote attacker to inject an arbitrary script via unspecified vectors.
Does this matter?
Lower severity and a low EPSS score (0.75%). Track it; it rarely justifies an emergency change on its own.
