CVE-2022-4260: WordPress WP-Ban <1.69.1 - Stored Cross-Site Scripting

id: CVE-2022-4260

info:
  name: WordPress WP-Ban <1.69.1 - Stored Cross-Site Scripting
  author: Hardik-Solanki
  severity: medium
  description: |
    WordPress WP-Ban plugin before 1.69.1 contains a stored cross-site scripting vulnerability. The plugin does not sanitize and escape some of its settings, which can allow high-privilege users to steal cookie-based authentication credentials and launch other attacks. This vulnerability can be exploited even when the unfiltered_html capability is disallowed, for example in multisite setup.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into the website, potentially leading to unauthorized access, data theft, or further compromise of the affected system.
  remediation: Fixed in version 1.69.1
