Vulnerability MAL-2026-17848

orderly-plugin-liquidity-heatmap poses as a liquidity heatmap plugin for the Orderly Network orderbook widget, but its only export is an empty stub and a postinstall hook runs node ./scripts/setup.js on npm install. When the script detects GitHub Actions (CI and GITHUB_WORKSPACE set), it records the runner's host, user, repository, GITHUB_/ACTIONS_/RUNNER_ variable names, GITHUB_TOKEN presence and length and network egress, and requests an OIDC token from ACTIONS_ID_TOKEN_REQUEST_URL. From 1.0.2 it uses the workflow's GITHUB_TOKEN to commit heatmap-setup-report.json to the default branch of the installing repository, and 1.0.4 also force-pushes a heatmap-setup-<timestamp> git tag with the credentials actions/checkout persists in .git/config; 1.0.6 ships the same setup.js as 1.0.4. The npm account dumtban published the six versions between 13:12 and 16:05 UTC on 2026-10-11, each extending the previous one's access to the CI runner.
