| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
CKSource CKEditor 5 version 35.4.0
Description
The issue is related to a cross-site scripting (XSS) vulnerability via the Full Featured CKEditor5 widget. It is noted that the vendor's position is that this is not a vulnerability, as the responsibility of choosing the correct security settings for their use case lies with the integrator adding CKEditor 5 functionality to a website. Safe default values are established, such as
config.htmlEmbed.showPreviews being set to false. The vulnerability may allow a remote attacker to conduct an XSS attack due to insufficient protection of the web page structure.Recommendations
For CKSource CKEditor 5 version 35.4.0, consider reviewing and adjusting the security settings according to the integrator's use case, ensuring safe default values are applied, such as setting
config.htmlEmbed.showPreviews to false. As a temporary workaround, consider restricting the use of the Full Featured CKEditor5 widget until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
