name: WordPress Plugin Stop Spammers 2021.8 - Reflected XSS
|
|
author: edoardottt

severity: medium
|
|
description: The Stop Spammers WordPress plugin before 2021.9 did not escape user input when blocking requests (such as matching a spam word), outputting it in an attribute after sanitising it to remove HTML tags, which is not sufficient and lead to a reflected Cross-Site Scripting issue.
