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 source supports an analytics SDK with no install lifecycle hook and no confirmed account hijacking behavior. The scanner’s high-severity browser-session hint was not substantiated by inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-07T14:17:09.501Z - **Finished:** 2026-10-07T14:17:36.103Z - **Download time:** 1280 ms - **Static scan time:** 1349 ms - **AI review time:** 23972 ms - **Total time:** 26602 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 concrete attack surface was identified. The flagged browser bundle contains analytics behavior, including input filtering and optional tracing instrumentation. - **Trigger:** Importing the SDK and invoking its analytics or tracing features. - **Impact:** No account-setting mutation, credential theft, or unrelated external reporting was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T14:17:36.103Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected code filters sensitive input types from capture and enables fetch or XHR tracing for supplied hostnames. - **Rationale:** The source supports an analytics SDK with no install lifecycle hook and no confirmed account hijacking behavior. The scanner’s high-severity browser-session hint was not substantiated by inspected source. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares no lifecycle scripts; its exports point to SDK entrypoints., dist/index.js excludes password, email, and other sensitive input types from capture., setIdentity() directs callers to use a stable internal user ID, not an email or session token., The tracing patch installs only for supplied hostnames; no browser account mutation was established. ## Affected versions and remediation This report applies to @heycatch/sdk@0.8.3. - Review the evidence and your use of @heycatch/sdk@0.8.3 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.
