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 user-invoked login path discloses Facebook session credentials to the package-default API without recipient-specific consent. The postinstall browser setup is benign but does not change this runtime credential transfer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-15T10:34:14.795Z - **Finished:** 2026-10-15T10:35:26.668Z - **Download time:** 1034 ms - **Static scan time:** 352 ms - **AI review time:** 70486 ms - **Total time:** 71873 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The login flow sends a Facebook session to the worker API. With the default configuration, that recipient is api.diggylab.com. - **Trigger:** A user invokes the login command and completes Facebook browser login or supplies Facebook cookies. - **Impact:** The API receives reusable Facebook session credentials, which could enable access to the associated account. - **Evidence paths:** worker.js - **Review source:** ai\_review - **Reviewed:** 2026-10-15T10:35:26.668Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The worker packages the Facebook session state and posts it to the API session endpoint. The default recipient is package-selected, and the source does not obtain recipient-specific consent before sending. - **Attack narrative:** When login completes, the worker sends the Facebook session to its API. The default API host is selected by the package, while the login flow does not ask the user to approve sending Facebook credentials to that recipient. Invoking Facebook login establishes consent to authenticate, not consent to disclose the session to the package-selected API. - **Rationale:** The user-invoked login path discloses Facebook session credentials to the package-default API without recipient-specific consent. The postinstall browser setup is benign but does not change this runtime credential transfer. - **Files touched:** worker.js - **Network endpoints:** api.diggylab.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The worker defaults its API recipient to api.diggylab.com; an operator who leaves the default in place gets that package-selected destination., The login command accepts Facebook cookies or completes a browser login, then reports that the Facebook session was sent to the server., The browser-login path passes the captured Facebook session to the shared upload function., The cookie-login path validates supplied Facebook cookies and uses the same upload function., The shared function sends the session state to the API, and the HTTP client posts it to the worker session endpoint using its configured origin., Production API origins are accepted when they use HTTPS, without a recipient allowlist binding them to a user-selected host. - **Evidence against:** The transfer requires the user to invoke login; the postinstall hook is limited to installing Playwright’s Chromium browser. ## Affected versions and remediation This report applies to diggylab-worker@0.1.35. - Avoid installing diggylab-worker@0.1.35. 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.
