How to Fix CVE-2026-22922

To remediate this vulnerability, upgrade all affected Apache airflow dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

apache-airflow fixed: 3.1.7 
pip install apache-airflow>=3.1.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show apache-airflow

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-22922, inspect your installed packages using pip:

pip show apache-airflow

Analyze the terminal output to locate any version of Apache airflow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.7), your application is affected.

Note: The pip show apache-airflow command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-648: Incorrect Use of Privileged APIs, where the product does not conform to the api requirements for a function call that requires extra privileges. this could allow attackers to gain privileges by causing the function to be called incorrectly. In Apache airflow, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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.
