id: CVE-2020-36510

info:
  name: WordPress 15Zine <3.3.0 - Cross-Site Scripting
  author: veshraj
  severity: medium
  description: |
    WordPress 15Zine before 3.3.0 is vulnerable to reflected cross-site scripting because the theme does not sanitize the cbi parameter before including it in the HTTP response via the cb_s_a AJAX action.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to execute malicious scripts in the context of a victim's browser, potentially leading to session hijacking, defacement, or theft of sensitive information.
  remediation: |
    Update WordPress 15Zine to version 3.3.0 or later to mitigate the vulnerability.
