  access to compromise the security of the system.

  - CVE-2024-48866: The improper handling of URL encoding (hex encoding) could allow remote
  attackers to cause the system to go into an unexpected state.

  - CVE-2024-48867, CVE-2024-48868: The improper neutralization of CRLF sequences (CRLF injection)
  could allow remote attackers to modify application data.

  - CVE-2024-50393: The command injection could allow remote attackers to execute arbitrary
  commands.

  remote attackers who have gained administrator access to obtain secret data or modify memory.");
