CVE-2022-28244 [Medium] | Privilege Escalation in Acrobat Dc

Acrobat Reader DC versions 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) is affected by a violation of secure design principles through bypassing the content security policy, which could result in an attacker sending arbitrarily configured requests to the cross-origin attack target domain. Exploitation requires user interaction in which the victim needs to access a crafted PDF file on an attacker's server.
