No install hook, unrelated endpoint, credential collection, or automatic account action was found. - **Network endpoints:** local.cs.dev ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes a CKEditor collaboration API and names dist/services.js as its main entry point., The WebSocket gateway accepts an API address and token as constructor inputs., Authentication sends the supplied token through the gateway's socket connection. - **Evidence against:** The inspected connection and authentication code uses the configured API address and has no unrelated collector host., The manifest contains no lifecycle scripts., The main bundle exports collaboration service classes; no import-time connection or unrelated automatic action was identified. ## Affected versions and remediation This report applies to @ckeditor/ckeditor-cloud-services-collaboration@55.2.1. - Review the evidence and your use of @ckeditor/ckeditor-cloud-services-collaboration@55.2.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
