Description

Apache Airflow Has an Authorization Bypass That Allows Unauthorized Task Log Access

Vulnerability Overview

An authorization bypass vulnerability exists in Apache Airflow that allows authenticated users to access task execution logs without the required permissions.

The Flaw

The vulnerability affects environments using custom roles or granular permission settings. Normally, Airflow allows administrators to separate "Task" access (viewing the task state) from "Task Log" access (viewing the console output/logs).

In affected versions, the permission check for retrieving logs is insufficient. An authenticated user who has been granted access to view Tasks can successfully request and view Task Logs, even if they do not have the specific can_read permission for Logs.

Impact

  • Confidentiality Loss: Task logs often contain sensitive operational data, debugging information, or potentially leaked secrets (environment variables, connection strings) that should not be visible to all users with basic task access.
  • Broken Access Control: This bypasses the intended security model for restricted user roles.

Affected Versions

  • Apache Airflow 3.1.0 through 3.1.6

Patches

Users should upgrade to Apache Airflow 3.1.7 or later, which enforces the correct permission checks for log access.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: None.
  • Availability impact: None.
