Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The bundle contains reviewer-directed language that attempts to suppress analysis, which is evidence of malicious intent under the review rules. The inspected runtime behavior otherwise appears consistent with the package’s collaboration purpose, and no concrete data theft or other runtime attack was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-30T06:16:42.524Z - **Finished:** 2026-10-30T06:17:18.196Z - **Download time:** 774 ms - **Static scan time:** 785 ms - **AI review time:** 34112 ms - **Total time:** 35672 ms The recorded confidence comes from the underlying analysis.

The inspected runtime connection requires an explicit connect call with a supplied API address and token; no unrelated endpoint or automatic connection was identified. - **Rationale:** The bundle contains reviewer-directed language that attempts to suppress analysis, which is evidence of malicious intent under the review rules. The inspected runtime behavior otherwise appears consistent with the package’s collaboration purpose, and no concrete data theft or other runtime attack was found. ### Review decision - **Verdict:** Malicious - **Confidence:** 82.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The bundle tells reviewers that deobfuscation or disassembly is forbidden and threatens legal consequences, attempting to discourage source analysis., The manifest identifies the package as CKEditor Cloud Services Collaboration and points to dist/services.js as its main entry point., The bundle’s WebSocket connection is created through an explicit connect call using a supplied API address and token. - **Evidence against:** The manifest declares no lifecycle scripts; the bundle imports collaboration and networking dependencies consistent with the package description., The inspected connection code uses a caller-supplied API address and token; no unrelated collector or automatic import-time connection was identified. ## Affected versions and remediation This report applies to @ckeditor/ckeditor-cloud-services-collaboration@55.3.0. - Avoid installing @ckeditor/ckeditor-cloud-services-collaboration@55.3.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
