  name: Dompdf < v0.6.0 - Local File Inclusion
  author: 0x_Akoko,akincibor,ritikchaddha
  severity: medium
  description: |
    A vulnerability in dompdf.php in dompdf before 0.6.1, when DOMPDF_ENABLE_PHP is enabled, allows context-dependent attackers to bypass chroot protections and read arbitrary files via a PHP protocol and wrappers in the input_file parameter, as demonstrated by a php://filter/read=convert.base64-encode/resource in the input_file parameter.
  impact: |
    The vulnerability can lead to unauthorized access to sensitive files, remote code execution, and compromise of the affected system.
  remediation: |
    Upgrade Dompdf to a version higher than v0.6.0 to mitigate the vulnerability.
