During an internal security audit, we noticed that users were potentially able to execute Javascript code by inserting it into a phone field or into a field that is used as a reference in linked fields. This could have happened by bypassing the profile's save action and changing values, for example telephone numbers.

Affected are the apps Linchpin User Profiles up to and including version 3.1.1, Linchpin Intranet Suite up to and including version 5.1.0 and Linchpin Essentials up to and including version 2.1.0.


The vulnerability is rated as 8.7 according to CVSS. The score is calculated as CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N.


There is no workaround but your system is not affected if you do not use the "phone" profile field or the linking feature of the "text" profile field.


For Linchpin User Profiles customers: Update to Linchpin User Profiles version 3.1.3 or later.

For Linchpin Essentials customers: Update to Linchpin Essentials 2.1.1 or later.

For Linchpin Suite customers: Update to Linchpin Suite 5.1.1 or later.
