info:
  name: WordPress Welcart e-Commerce <2.8.5 - Arbitrary File Access
  author: theamanrawat
  severity: high
  description: |
    WordPress Welcart e-Commerce plugin before 2.8.5 is susceptible to arbitrary file access. The plugin does not validate user input before using it to output the content of a file, which can allow an attacker to read arbitrary files on the server, obtain sensitive information, modify data, and/or execute unauthorized operations.
  remediation: Fixed in version 2.8.5.
