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 explicit login path transfers Facebook session cookies to the package's default API, a recipient separate from Facebook, without recipient-specific consent. Because the cookies can authenticate the Facebook account, this is concrete credential disclosure. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-15T12:02:30.758Z - **Finished:** 2026-10-15T12:03:54.033Z - **Download time:** 510 ms - **Static scan time:** 340 ms - **AI review time:** 82424 ms - **Total time:** 83275 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 Facebook session cookies to the worker API. The default API is api.diggylab.com, and the configured HTTPS destination is not restricted to an approved host. - **Trigger:** An operator invokes the worker login command and completes Facebook login or supplies Facebook cookies. - **Impact:** The API recipient receives reusable Facebook session cookies without a recipient-specific consent step. - **Evidence paths:** worker.js - **Review source:** ai\_review - **Reviewed:** 2026-10-15T12:03:54.033Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** After validating the session, the worker POSTs its serialized storage state to the configured API's worker session endpoint. - **Attack narrative:** When login completes, the worker uploads the Facebook session to the configured API before saving a local copy. The default recipient is api.diggylab.com, and another HTTPS host can be configured without a recipient allowlist. The login flow does not ask the operator to confirm disclosure to that recipient. - **Rationale:** The explicit login path transfers Facebook session cookies to the package's default API, a recipient separate from Facebook, without recipient-specific consent. Because the cookies can authenticate the Facebook account, this is concrete credential disclosure. - **Files touched:** worker.js - **Network endpoints:** https://api.diggylab.com/worker-node/session ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The login flow obtains a Facebook session through browser login or supplied cookies, then passes it to the session upload helper., The helper sends the session data in a POST to the worker session endpoint; requests use the configured API origin., The default recipient is api.diggylab.com. The API origin can be set by the caller, and packaged destinations are accepted over HTTPS without a host allowlist., The code saves a local session copy after the upload; the login flow has no recipient-specific consent check. - **Evidence against:** The transfer happens when the operator invokes login, and the worker validates the Facebook session before uploading it. ## Affected versions and remediation This report applies to diggylab-worker@0.1.36. - Avoid installing diggylab-worker@0.1.36. 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.
