What is CVE-2026-75157?

The vulnerability in Apache Airflow arises from an oversight in permission checks for the asset queued-events DELETE endpoints. Instead of validating the caller's Dag-axis permission for EDIT, it incorrectly checks for READ permission. This allows any authenticated user with read access to a Dag to delete the queued asset events associated with that Dag, potentially disrupting scheduled asset-triggered actions. This issue becomes particularly critical in deployments where asset-triggered scheduling is actively utilized, and the misconfiguration of permissions is prevalent. To mitigate this vulnerability, upgrading to Apache Airflow version 3.3.2 or later is highly recommended.

Affected Version(s)

Apache Airflow 0 < 3.3.2

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
