CiviCRM did not provide sufficient protection on the CKEditor configuration form, which could allow a malicious third-party to trick a CiviCRM administrator into changing the configuration.

Note: This form had another vulnerability in the same version. The risk from two overlapping vulnerabilities may be greater than the risk of each individually.

Security Risk
Critical
Vulnerability
Cross Site Request Forgery
Affected Versions

Fixed Versions

CiviCRM version 5.28.1 and 5.27.5 ESR

Publication Date
Solutions

Upgrade to the latest version of CiviCRM or use a different editor other than CKEdtior included with Core
