CVE-2020-7936
An open redirect on the login form (and possibly other places) in Plone 4.0 through 5.2.1 allows an attacker to craft a link to a Plone Site that, when followed, and possibly after login, will redirect to an attacker's site.
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
