CVE-2025-54415dag-factory's CI/CD Workflow Allows for Repository Takeover and Secret Exfiltration
Critical 9.1
In plain English
A critical-severity OS command injection in dag-factory from astronomer. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.8% (higher than 55% of all known vulnerabilities). Ready-made attack tooling exists: public proof-of-concept code.
Official description
dag-factory is a library for Apache Airflow® to construct DAGs declaratively via configuration files. In versions 0.23.0a8 and below, a high-severity vulnerability has been identified in the cicd.yml workflow within the astronomer/dag-factory GitHub repository. The workflow, specifically when triggered by pull_request_target, is susceptible to exploitation, allowing an attacker to execute arbitrary code within the GitHub Actions runner environment. This misconfiguration enables an attacker to establish a reverse shell, exfiltrate sensitive secrets, including the highly-privileged GITHUB_TOKEN, and ultimately gain full control over the repository. This is fixed in version 0.23.0a9.
