## Source: amazon-inspector (ed5d0e26b18d32568569b828bdbe2ccb40d0c4a54780c6e51be6280cb5fc851f) @flexmr/survey-client@10.0.12 declares its sole dependency 'marker-index-symbol-schema' as a bare HTTPS URL to https://artifacts.creditslib.com/npm/marker-index-symbol-schema instead of a registry version range. On npm install, npm fetches whatever bytes that URL returns and executes any lifecycle scripts contained in them, with no version pin, no hash, and no integrity check. The shipped index.js is a one-line re-export stub (module.exports = require('marker-index-symbol-schema')), so the external host is the entire payload surface and whoever controls artifacts.creditslib.com controls code executed on every installer's machine. The package also carries dependency-confusion markers that aggravate the delivery vector: a vendor-looking scope (@flexmr/survey-client) paired with placeholder metadata (description 'Generated package', author 'Package Registry', repository URL under github.com/example/...), none of which are consistent with a legitimate @flexmr-published client. The artifacts.creditslib.com host is unrelated to any npm registry or to the @flexmr publisher. --- Credit: [OpenSS

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
