CVE-2021-39857
Adobe Acrobat Reader DC add-on for Internet Explorer versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by an Information Disclosure vulnerability.
Does this matter?
Lower severity and a low EPSS score (2.52%). Track it; it rarely justifies an emergency change on its own.
