id: CVE-2022-0189

info:
  name: WordPress RSS Aggregator < 4.20 - Authenticated Cross-Site Scripting
  author: DhiyaneshDK
  severity: medium
  description: WordPress RSS Aggregator < 4.20 is susceptible to cross-site scripting. The plugin does not sanitize and escape the id parameter in the wprss_fetch_items_row_action AJAX action before outputting it back in the response, leading to reflected cross-site scripting.
  impact: |
    An attacker with authenticated access can inject malicious scripts into the website, potentially leading to session hijacking, defacement, or theft of sensitive information.
  remediation: |
    Update WordPress RSS Aggregator plugin to version 4.20 or later to mitigate the vulnerability.
