CVE-2021-20784
HTTP header injection vulnerability in Everything version 1.0, 1.1, and 1.2 except the Lite version may allow a remote attacker to inject an arbitrary script or alter the website that uses the product.
Does this matter?
Lower severity and a low EPSS score (1.12%). Track it; it rarely justifies an emergency change on its own.
