CVE-2025-67727
📋 TL;DR
This CVE describes a GitHub Actions workflow vulnerability in Parse Server that grants elevated permissions to CI/CD pipelines. It allows unauthorized access to GitHub secrets and write permissions, potentially enabling code injection from forks or lifecycle scripts. Only repositories using GitHub Actions for CI/CD are affected, including public forks with Actions enabled.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal GitHub secrets, inject malicious code into the repository, compromise the CI/CD pipeline, and potentially gain persistent access to the development infrastructure.
Likely Case
Unauthorized access to GitHub secrets leading to credential theft, potential code injection in CI/CD workflows, and compromise of the repository's build/deploy process.
If Mitigated
Limited to repository forks with Actions enabled, with no direct impact on production Parse Server deployments if proper secrets management and access controls are in place.
🎯 Exploit Status
Exploitation requires access to create or modify GitHub Actions workflows, typically through repository forks or compromised contributor accounts.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.6.0-alpha.2
Vendor Advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-6w8g-mgvv-3fcj
Restart Required: No
Instructions:
1. Update Parse Server to version 8.6.0-alpha.2 or later. 2. Apply commits 6b9f8963cc3debf59cd9c5dfc5422aff9404ce9d and e3d27fea08c8d8bdd9770a689bc2d757cda48b66. 3. Review and update GitHub Actions workflows to ensure proper permission scoping.
🔧 Temporary Workarounds
Disable GitHub Actions in Forks
allDisable GitHub Actions in repository forks to prevent exploitation through forked workflows.
Navigate to repository Settings > Actions > General > Disable Actions for forked repositories
Restrict GitHub Secrets Access
allReview and restrict GitHub secrets access in workflows, using minimal required permissions.
Review .github/workflows/*.yml files and set permissions: read-only where possible
🧯 If You Can't Patch
- Review and audit all GitHub Actions workflows for excessive permissions
- Rotate all GitHub secrets and credentials that may have been exposed
🔍 How to Verify
Check if Vulnerable:
Check if using Parse Server version < 8.6.0-alpha.2 and review GitHub Actions workflow files for permission settings.Check Version:
npm list parse-server | grep parse-serverVerify Fix Applied:
Verify Parse Server version is >= 8.6.0-alpha.2 and that commits 6b9f896 and e3d27fe are applied.📡 Detection & Monitoring
