CVE-2019-12766
This leads to XSS attack vectors.
MEDIUM 6.1EPSS 0.92%
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in Joomla! before 3.9.7. The subform fieldtype does not sufficiently filter or validate input of subfields. This leads to XSS attack vectors.
