  author: s4e-io
  severity: high
  description: |
    The PDF Generator Addon for Elementor Page Builder plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.7.5 via the rtw_pgaepb_dwnld_pdf() function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.
  impact: |
    Unauthenticated attackers can exploit path traversal to read arbitrary files on the server, potentially exposing sensitive configuration files, wp-config.php containing database credentials, and other critical system files.
  remediation: |
    Update PDF Generator Addon for Elementor Page Builder plugin to a version later than 1.7.5 that properly validates and sanitizes file paths in the rtw_pgaepb_dwnld_pdf function.
