CVE-2026-47174

Duck Site: Untrusted pull request code can trigger privileged production deployment

Published Jun 11, 2026 CVSS 4.0 · 9.5 Critical EPSS < 1% KEV · Not listed
Description
In Duck Site before version 1.0.1, the repository has a deploy workflow that runs after the build workflow completes. The build workflow runs on pull requests, while the deploy workflow runs with package-write permissions and deployment secrets. If an attacker can make a pull request build satisfy the deploy workflow’s main branch condition, the deploy job checks out the triggering workflow commit, builds it into a Docker image, pushes it as latest, and triggers Dokploy deployment. This can allow attacker-controlled pull request code to become the deployed production site image without being merged. This issue has been patched in version 1.0.1.
