Project: Select (or other) [1] Date: 2018-July-25 Security risk: *Moderately critical* 14∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Cross Site Scripting

Description:  This module enables users to select 'other' on certain form elements and a textfield appears for the user to provide a custom value.

The module doesn't sufficiently escape values of a text field the under the scenario when "Select or other" formatter is used.

This vulnerability is mitigated by the fact that an attacker must have access to edit a field that is displayed through the "Select or other" formatter.

Solution:  * If you use the "Select or other" 7.x-2.x, upgrade to Select or other 7.x-2.24 [3] * If you use the "Select or other" 7.x-3.x, upgrade to Select or other 7.x-3.0-alpha3 [4]
