CVE-2026-75157 is an improper authorization vulnerability in Apache Airflow versions before 3.3.2. The asset queued-events DELETE endpoints validate Dag-axis READ permission rather than the required EDIT permission. As a result, an authenticated user authorized only to view a DAG can perform the state-changing operation of deleting that DAG's queued asset events. Deletion of these events silently suppresses asset-triggered scheduling for the affected DAG.

The repository contains a README and one Python entry point, poc.py. The script is a generic, bounded HTTP request harness intended to demonstrate CVE-2026-75157 against Apache Airflow releases before 3.3.2. It constructs a caller-selected HTTP(S) request, supports GET/POST/PUT/PATCH/DELETE/HEAD methods, custom headers, bearer tokens loaded from an environment variable, JSON or file-backed request bodies, redirect control, timeouts, and status/body assertions. It redacts sensitive headers in its JSON output. The documented exploit use is an authenticated DELETE request to an Airflow DAG queued-events route. It demonstrates that a user granted DAG read and Assets delete permissions can delete a queued event without DAG edit permission because affected routes authorize the DAG axis at read rather than edit level. The script defaults to refusing non-loopback targets, but its --allow-non-loopback option permits authorized remote testing. It does not scan, enumerate targets, create accounts, establish persistence, or include a shell/command-execution payload.
