  name: The Events Calendar 6.15.12 - 6.16.2 - Unauthenticated Blind SQL Injection
  author: HaroonArshad-53
  severity: critical
  description: |
    The Events Calendar WordPress plugin versions 6.15.12 through 6.16.2 do not properly validate the order parameter of the experimental tec/v1 REST events endpoint, allowing unauthenticated attackers to run blind SQL queries and extract arbitrary database contents.
  impact: |
    Attackers can execute arbitrary SQL queries, potentially leading to data disclosure or modification.
  remediation: |
    Upgrade to a version later than 6.16.2 or the latest available version.
