Detailsinfo

A vulnerability classified as critical has been found in astronomer dag-factory up to 0.23.0a8. This affects the function pull_request_target. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
