Technical Description
Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through 5.8.22, a stored Cross-site Scripting (XSS) vulnerability exists in the `editableTable.twig` component when using the `html` column type. The application fails to sanitize the input, allowing an attacker to execute arbitrary JavaScript when another user views a page with the malicious table field. In order to exploit the vulnerability, an attacker must have an administrator account, and `allowAdminChanges` must be enabled in production, which is against Craft's security recommendations. Versions 4.16.19 and 5.8.23 patch the issue.
Remediation
Check the references section for vendor advisories and patches from craftcms. Update craft_cms to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
