CVE-2026-40961

7.2 · HIGH
Published Jun 1, 2026 apache CWE-601

Overview

CVE-2026-40961 is a high-severity vulnerability affecting apache airflow. It was published on June 1, 2026 and has a CVSS 3.1 base score of 7.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.2, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the `is_safe_url` check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to `apache-airflow` 3.2.2 or later. As a defense-in-depth mitigation, deployment operators can place Airflow behind a reverse proxy that strips off-domain `next=` query parameters before they reach the login endpoint.

Remediation

Check the references section for vendor advisories and patches from apache. Update airflow to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
