Summary
Directus's webhook trigger flows can leak sensitive data
Details

Describe the Bug

In Directus, when a Flow with the "Webhook" trigger and the "Data of Last Operation" response body encounters a ValidationError thrown by a failed condition operation, the API response includes sensitive data. This includes environmental variables, sensitive API keys, user accountability information, and operational data.

This issue poses a significant security risk, as any unintended exposure of this data could lead to potential misuse.

To Reproduce

Steps to Reproduce:

  1. Create a Flow in Directus with:
    • Trigger: Webhook
    • Response Body: Data of Last Operation
  2. Add a condition that is likely to fail.
  3. Trigger the Flow with any input data that will fail the condition.
  4. Observe the API response, which includes sensitive information like:
    • Environmental variables ($env)
    • Authorization headers
    • User details under $accountability
    • Previous operational data.

Expected Behavior: In the event of a ValidationError, the API response should only contain relevant error messages and details, avoiding the exposure of sensitive data.

Actual Behavior: The API response includes sensitive information such as:

  • Environment keys (FLOWS_ENV_ALLOW_LIST)
  • User accountability (role, user, etc.)
  • Operational logs (current_payments, $last), which might contain private details.
