Detailsinfo

A vulnerability was found in duck-organization duck-site up to 1.0.0. It has been classified as critical. Affected is some unknown functionality of the component Pull Request Handler. The manipulation with an unknown input leads to a inclusion of functionality from untrusted control sphere vulnerability. CWE is classifying the issue as CWE-829. The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
