CVE-2021-46087

Status: ModifiedMedium (5.4)—

In jfinal_cms >= 5.1 0, there is a storage XSS vulnerability in the background system of CMS. Because developers do not filter the parameters submitted by the user input form, any user with background permission can affect the system security by entering malicious code.

CVSS
