Vulnerability Vulnerable Version

Vulnerability	Vulnerable Version
C Open Redirect Affected versions of this package are vulnerable to Open Redirect via the admin preview iframe URL resolution in `resolvePreviewPath` (and the former `getExpectedPreviewOrigin`). The admin preview feature loads a page in an iframe and derives the trusted postMessage origin from the preview URL supplied in the route splat parameter. An attacker can craft a link containing an off-origin URL - using forms such as a leading double slash, backslash separators, or a leading tab character - which the URL parser resolves to an external origin, causing the iframe to load a third-party page and establishing a trusted postMessage channel with that external origin, enabling cross-site content injection and data exfiltration. How to fix Open Redirect? Upgrade `@tinacms/app` to version 2.5.14 or higher.	<2.5.14
H Improper Verification of Source of a Communication Channel Affected versions of this package are vulnerable to Improper Verification of Source of a Communication Channel via improper validation of cross-origin messages in the `window` message listeners. An attacker can hijack authenticated editing sessions by sending crafted postMessage events from a malicious origin. How to fix Improper Verification of Source of a Communication Channel? Upgrade `@tinacms/app` to version 2.5.6 or higher.	<2.5.6
