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 source implements a browser bug-reporting SDK: capture begins after init(), report data goes to the configured API, and the documented collection is consistent with that purpose. The scanner’s account-hijack lead was not substantiated; no unrelated account mutation or credential destination was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-03T10:39:30.716Z - **Finished:** 2026-11-03T10:40:13.073Z - **Download time:** 767 ms - **Static scan time:** 1228 ms - **AI review time:** 40360 ms - **Total time:** 42357 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 attack identified; behavior matches a browser bug-report SDK. - **Trigger:** The consumer calls init(); capture hooks then run, and reports are sent when the integration or reporter submits one. - **Impact:** Expected diagnostic reporting and project usage metadata; no unrelated credential collection or account mutation was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-03T10:40:13.073Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK captures disclosed diagnostic data and sends it to the configured BugCatch API. Its periodic hello request sends project and SDK metadata to that same configured API. - **Rationale:** The inspected source implements a browser bug-reporting SDK: capture begins after init(), report data goes to the configured API, and the documented collection is consistent with that purpose. The scanner’s account-hijack lead was not substantiated; no unrelated account mutation or credential destination was found. - **Files touched:** src/index.js, src/collectors.js, src/identity.js - **Network endpoints:** configured apiBase/ingest/hello, configured apiBase/ingest/bugs, http://localhost:3000 (default apiBase) ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The only lifecycle hook is prepublishOnly, which builds the package; there is no install hook., The README discloses that console, network metadata, errors, and environment are captured after init(), and says request bodies are not read., Capture hooks are installed during init() and controlled by capture options., The hello request reports limited project and SDK metadata to the configured API base once per day., Bug reports are posted to the configured API base through the documented ingest endpoint. - **Evidence against:** Console, network, and error capture are enabled by default after init()., The SDK sends an automatic hello request after init(), once per day per browser and project. ## Affected versions and remediation This report applies to @sphoro/bugcatch-web-sdk@0.19.0. - Review the evidence and your use of @sphoro/bugcatch-web-sdk@0.19.0 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.
