AI risk analysis

Summary: The flaw allows an attacker to inject and execute arbitrary scripts via administrator-controlled descriptions, potentially compromising the viewing administrator's session.
Exploitability: Exploitation is moderately hard as it requires an attacker to control the description and an administrator to view the affected row. Precondition is the presence of an unpatched version prior to 3.6.5.
Blast radius: If exploited, the impact is high as it can compromise the session of the viewing administrator and enable cross-privilege actions.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Vendure 3.6.5 or later.

NVD description

Vendure is an open-source headless commerce platform. Prior to 3.6.5, RichTextDescriptionCell in packages/dashboard/src/lib/components/shared/table-cell/order-table-cell-components.tsx attempts to strip markup by assigning an administrator-controlled description to a live element's innerHTML and then reading textContent. Active resource markup can execute an event handler during the innerHTML assignment before textContent is read. A lower-privilege administrator can store such markup in descriptions rendered by the Products list, Collections list, Promotions list, Payment Methods list, or Shipping Methods list, and script executes when another administrator views the affected row. This stored cross-site scripting can compromise the viewing administrator's session and enable cross-privilege or cross-channel administrative actions. This issue is fixed in version 3.6.5.
