Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package is not confirmed malicious: the behavior is confined to its BrowserStack runtime flow and there is no install hook or demonstrated theft. However, automatically executing an unverified remotely supplied binary is an unresolved dangerous capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-12T13:20:13.668Z - **Finished:** 2026-09-12T13:21:25.388Z - **Download time:** 767 ms - **Static scan time:** 4279 ms - **AI review time:** 66673 ms - **Total time:** 71720 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:** During BrowserStack service bootstrap, the package can download a CLI archive, write an executable under its BrowserStack directory, and run it. The downloaded artifact is not integrity-pinned in the inspected source. - **Trigger:** Running WebdriverIO with this BrowserStack service enabled. - **Impact:** A compromised update response or configured binary URL could cause execution of an untrusted native binary. - **Evidence paths:** build/index.js, build/cleanup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T13:21:25.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote CLI update, local extraction, and child-process execution. - **Rationale:** The package is not confirmed malicious: the behavior is confined to its BrowserStack runtime flow and there is no install hook or demonstrated theft. However, automatically executing an unverified remotely supplied binary is an unresolved dangerous capability. - **Files touched:** build/index.js, build/cleanup.js, ~/.browserstack/cli/binary-\* - **Network endpoints:** api.browserstack.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** At service runtime, the updater accepts a binary URL returned by its update service and can replace it with an environment-supplied URL., The service resolves that CLI path and spawns it as a child process., The package has no npm install lifecycle hook; this behavior requires service runtime. - **Evidence against:** The binary-management behavior is tied to the BrowserStack service bootstrap rather than package installation., No source evidence of secret harvesting, unrelated file collection, destructive project changes, or reviewer manipulation was found. ## Affected versions and remediation This report applies to @wdio/browserstack-service@9.36.0. - Review the evidence and your use of @wdio/browserstack-service@9.36.0 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.
