  "details": "A weakness has been identified in invoiceninja Invoice Ninja up to 5.13.26. This affects an unknown part of the file /vedor/profile/ of the component Vendor Portal Profile Update. Executing a manipulation of the argument vendor_contact can lead to authorization bypass. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. Upgrading to version 5.13.27 is able to mitigate this issue. This patch is called f86fd9697ce7bd0d28adbe2e6c5890780482ea90. The affected component should be upgraded.",
