What is CVE-2026-56383?

Craft CMS has a stored cross-site scripting (XSS) vulnerability in the editableTable.twig component. When utilizing the 'Row Heading' column type, input values are not properly sanitized. This security lapse allows an attacker, assuming an administrator account with 'allowAdminChanges' enabled, to inject arbitrary JavaScript. The malicious script is executed whenever another user views the page containing the compromised table field. It is crucial to update to versions 4.16.19 or 5.8.23 to mitigate this risk.

Affected Version(s)

cms 4.5.0-beta.1 < 4.16.19

cms 5.0.0-RC1 < 5.8.23

cms 4.16.19
