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 vision token is sent to a package-selected default endpoint rather than a recipient validated against the intended service. The source confirms conditional exposure but does not establish malicious use, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-22T11:23:48.453Z - **Finished:** 2026-10-22T11:25:04.767Z - **Download time:** 517 ms - **Static scan time:** 271 ms - **AI review time:** 75526 ms - **Total time:** 76314 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:** Configured image recognition sends a Gemini-labeled token to the package’s default vision API host. This creates conditional token exposure, though the source does not establish the host’s ownership or misuse. - **Trigger:** An image arrives in an enabled group after the vision token, base URL, and model are configured. - **Impact:** The configured token is disclosed to the API recipient. Its ownership and handling are unresolved. - **Evidence paths:** lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T11:25:04.767Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin sends the image and a bearer authorization token to the resolved vision API endpoint; the default base URL is wxls.cc.cd. - **Rationale:** The vision token is sent to a package-selected default endpoint rather than a recipient validated against the intended service. The source confirms conditional exposure but does not establish malicious use, so this warrants a warning rather than a block. - **Network endpoints:** https://wxls.cc.cd ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The vision API defaults to wxls.cc.cd; its token setting is empty by default and described as a Gemini interface token., The vision request sends the configured token as a bearer header with image data to the configured base URL., Image recognition returns without sending when its base URL, token, or model is missing., Recording an incoming image invokes image recognition., The middleware records messages only in enabled groups, and image recognition can be activated by an image message there. - **Evidence against:** The token must be supplied in configuration before the vision request runs; the source does not establish who operates wxls.cc.cd or how it uses the token. ## Affected versions and remediation This report applies to koishi-plugin-smmcat-yeyechat@0.1.21. - Review the evidence and your use of koishi-plugin-smmcat-yeyechat@0.1.21 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.
