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 source supports a warning for conditional forwarding of an existing service credential to an unrestricted configured destination. The scanner's environment signal is ordinary bundled functionality, and no block-eligible attack was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-04T10:15:30.969Z - **Finished:** 2026-10-04T10:16:59.111Z - **Download time:** 510 ms - **Static scan time:** 688 ms - **AI review time:** 86942 ms - **Total time:** 88142 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 saved service token can be forwarded to a different configured API destination. This establishes conditional credential exposure, but no confirmed malicious attack. - **Trigger:** Initialize with a different baseUrl while a valid session cookie for the same subject exists, then invoke authenticated operations or session closure. - **Impact:** An alternate endpoint could receive an existing Kasookoo session token if the browser permits the request. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-04T10:16:59.111Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cookie restoration does not check the issuing destination; requests attach the restored token as bearer authentication to the configured base URL. - **Rationale:** The source supports a warning for conditional forwarding of an existing service credential to an unrestricted configured destination. The scanner's environment signal is ordinary bundled functionality, and no block-eligible attack was established. - **Network endpoints:** https://sdk-test.kasookoo.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json has build scripts but no automatic install lifecycle hooks., Session restoration accepts a saved cookie token based on subject and expiry without binding it to the original API destination., The API base URL accepts a caller-configured value without a destination allowlist., Session closure sends the restored token as bearer authentication to the configured API destination., Explicit widget initialization starts session restoration and supplies its token to call handling., The flagged dialer environment access controls bundled BigInt support. - **Evidence against:** The default API and monitoring destinations belong to Kasookoo., No covert recipient, shell execution, or malicious install behavior was identified. ## Affected versions and remediation This report applies to kasookoo-click-to-call-widget@0.1.0-beta.15. - Review the evidence and your use of kasookoo-click-to-call-widget@0.1.0-beta.15 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.
