Because the token is bound to the user and action rather than to a specific block, page, or form, an authenticated user with edit access to one Express Form could reuse a validly obtained token to add, modify, or delete controls on Express Forms they were not authorized to edit, including injecting a control whose value is later rendered as HTML to achieve stored XSS. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.0 with vector CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:P/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N. Thanks Yat Wu for reporting.</p> <p><strong>Affected:</strong> Concrete CMS</p> <p>Concrete CMS 9.0.0 through 9.5.2 did not enforce a block-level edit-permission check on the Express Form block&#39;s control-management actions, which relied solely on CSRF token validation.
