What is CVE-2026-47174?
CVE-2026-47174 is a critical code injection vulnerability in duck-organization duck-site, published on 11 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
