The Email Subscribers by Icegram Express WordPress plugin before 5.7.45 does not sanitise and escape some of its Text Block options, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
