Automated research artifact — not the upstream project.
This repository is a disposable lab built by an automated harness for a master's thesis at Université Laval on reproducing published GitHub Actions workflow vulnerabilities. It is a verbatim snapshot of
MIC-DKFZ/nnUNetat commit9a1db0dd1c74894fa17e79014be4097f546a51be(2026-04-24), redistributed under that project's own licence, whose file is included unchanged in this snapshot.The upstream project is not involved, is never targeted, and the vulnerability studied here is already public. Every secret and variable in this repository is a randomly generated dummy value — no real credential is present. Action references and runner images are pinned to what they resolved to on 2026-04-24; see
pinning.mdin the harness output for every change made to the snapshot.Questions or objections: [email protected]
