Operational restrictions bypass vulnerability in E-mail of Cybozu Garoon 4.0.0 to 5.0.2 allows a remote authenticated attacker to alter the data of Portal without the appropriate privilege.
Does this matter?
Lower severity and a low EPSS score (0.82%). Track it; it rarely justifies an emergency change on its own.
