Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The inspected entrypoints implement BrowserStack testing, diagnostics, and CLI management without an installation attack chain. No concrete credential diversion, broad agent-control mutation, or malicious persistence was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-30T18:41:40.617Z - **Finished:** 2026-09-30T18:44:41.853Z - **Download time:** 1040 ms - **Static scan time:** 4805 ms - **AI review time:** 175390 ms - **Total time:** 181236 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:** No confirmed attack was identified. Inspected credential handling, diagnostic uploads, subprocesses, and cleanup support the BrowserStack testing integration. - **Trigger:** Configured WebdriverIO test runs and argument-controlled cleanup activate these operations. - **Impact:** Testing operations create logs and caches and transmit diagnostics to BrowserStack; no concrete malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-09-30T18:44:41.853Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The service authenticates BrowserStack requests, uploads diagnostic archives, and manages its testing CLI. - **Rationale:** The inspected entrypoints implement BrowserStack testing, diagnostics, and CLI management without an installation attack chain. No concrete credential diversion, broad agent-control mutation, or malicious persistence was established. - **Files touched:** logs/bstack-wdio-service.log, log/sdk-cli-debug.log - **Network endpoints:** https://api.browserstack.com, https://collector-observability.browserstack.com, https://upload-observability.browserstack.com ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no install lifecycle hooks or runtime dependency on itself., build/cleanup.js requires upload arguments and BrowserStack credentials before uploading service logs., build/index.js sends log archives to BrowserStack observability endpoints., Captured test configuration passes through sensitive-content redaction., Regional endpoint updates come from the BrowserStack CLI session response., Subprocess execution starts the testing SDK CLI, and archive extraction rejects paths outside its directory. ## Affected versions and remediation This report applies to @wdio/browserstack-service@9.39.2. - Review the evidence and your use of @wdio/browserstack-service@9.39.2 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.
