Parse Server ist ein Open-Source-Backend, das auf jeder Infrastruktur bereitgestellt werden kann, die Node.js ausführt. In Versionen vor 8.6.0-alpha.2 wird ein GitHub CI-Workflow auf eine Weise ausgelöst, die dem GitHub Actions-Workflow erhöhte Berechtigungen gewährt, wodurch dieser Zugriff auf GitHub-Secrets und Schreibberechtigungen erhält, die im Workflow definiert sind. Potenziell kann Code aus einem Fork oder Lifecycle-Skripts enthalten sein. Nur die CI/CD-Infrastruktur des Repositorys ist betroffen, einschließlich aller öffentlichen GitHub-Forks mit GitHub A

The primary impact of CVE-2025-67727 is the potential for unauthorized access to sensitive information and the ability to execute arbitrary code within the CI/CD environment. An attacker could leverage this vulnerability to steal API keys, database credentials, or other secrets stored as GitHub Actions workflow variables. Furthermore, they could inject malicious code into the Parse Server application, leading to data breaches, service disruption, or even complete compromise of the system. The vulnerability specifically targets repositories utilizing GitHub Actions for CI/CD, including public forks, expanding the potential blast radius significantly. This resembles previous supply-chain attacks where CI/CD pipelines were exploited to inject malicious code.

Organizations utilizing Parse Server for their backend infrastructure and relying on GitHub Actions for CI/CD are at significant risk. This includes startups, enterprises, and open-source projects that have deployed Parse Server and enabled GitHub Actions for automated builds and deployments. Legacy configurations and repositories with permissive GitHub Actions permissions are particularly vulnerable.

• github / workflows: Examine GitHub Actions workflows for unusual permission configurations or suspicious code execution.

# Example: Check for workflows with elevated permissions
permissions:
  contents: read # Restrict to read-only access where possible
  actions: read

• github / repository: Monitor repository activity for unexpected changes or code modifications, especially within CI/CD related directories. • generic web: Review GitHub Actions logs for any unauthorized access attempts or suspicious activity. • linux / server: Examine system logs for any unusual processes or network connections originating from the CI/CD environment.

The primary mitigation for CVE-2025-67727 is to upgrade Parse Server to version 8.6.0-alpha.2 or later, which includes the necessary fixes. If immediate upgrading is not feasible, review and restrict the permissions granted to GitHub Actions workflows. Carefully examine the workflow definitions to ensure that no unnecessary secrets or elevated privileges are being assigned. Consider implementing stricter access controls and auditing the workflow execution logs for suspicious activity. While a WAF or proxy cannot directly mitigate this vulnerability, they can help detect and block malicious requests originating from compromised CI/CD pipelines. Verify the upgrade by inspecting the GitHub Actions workflow configuration and confirming that the elevated permissions have been removed.
