id: CVE-2022-0658

info:
  name: CommonsBooking < 2.6.8 - SQL Injection
  author: theamanrawat
  severity: critical
  description: |
    The plugin does not sanitise and escape the location parameter of the calendar_data AJAX action (available to unauthenticated users) before it is used in dynamically constructed SQL queries, leading to an unauthenticated SQL injection.
  impact: |
    Unauthenticated attackers can execute SQL injection via unsanitized AJAX parameters to extract database contents, potentially exposing sensitive WordPress data including user credentials.
  remediation: Fixed in version 2.6.8
