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. Source inspection establishes conditional forwarding of an existing service credential to an unrestricted configured destination. This warrants a warning under the credential-forwarding policy, while the scanner's environment signal does not establish malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-04T10:15:27.390Z - **Finished:** 2026-10-04T10:17:09.455Z - **Download time:** 513 ms - **Static scan time:** 757 ms - **AI review time:** 100793 ms - **Total time:** 102065 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:** A cached Kasookoo session token can be forwarded to a different caller-configured API destination. This establishes conditional credential exposure, without evidence of a deliberate attack. - **Trigger:** Initialize with a changed baseUrl while a valid session cookie for the same subject exists, then perform authenticated activity or destroy the widget. - **Impact:** The configured recipient could receive an existing service session token. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-04T10:17:09.455Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Session restoration omits destination binding; teardown uses the new baseUrl and sends the restored token as a bearer credential. - **Rationale:** Source inspection establishes conditional forwarding of an existing service credential to an unrestricted configured destination. This warrants a warning under the credential-forwarding policy, while the scanner's environment signal does not establish malware. - **Network endpoints:** https://sdk-test.kasookoo.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Cached session restoration checks subject and expiry but does not bind the token to its original API destination., Widget initialization accepts a configurable API destination and starts the session manager with it., Session teardown forwards the restored token to the configured destination through an authenticated DELETE request., The HTTP helper sends supplied tokens in the Authorization header., package.json has no automatic installation lifecycle hooks., The flagged dialer environment access controls BigInt support rather than harvesting environment secrets. - **Evidence against:** Default API and telemetry destinations belong to Kasookoo., Exposure requires a valid cached session, a changed API destination, initialization and subsequent authenticated activity; no covert attacker destination was identified. ## Affected versions and remediation This report applies to kasookoo-click-to-call-widget@0.1.0-beta.13. - Review the evidence and your use of kasookoo-click-to-call-widget@0.1.0-beta.13 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.
