Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The plugin sends a configured Gemini vision token to the unrelated default host \`wxls.cc.cd\` during automatic image recognition. Because the host is package-selected by default rather than explicitly set by the user for that service, this is credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-29T22:52:33.598Z - **Finished:** 2026-10-29T22:53:16.223Z - **Download time:** 520 ms - **Static scan time:** 396 ms - **AI review time:** 41708 ms - **Total time:** 42625 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 Gemini vision credentials are sent to a third-party default endpoint during image recognition. - **Trigger:** A configured vision token and model, followed by a message containing an image. - **Impact:** The endpoint receives the configured vision API credential and image content; that credential could be used to access its associated service. - **Evidence paths:** lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T22:53:16.223Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin uses the token as an Authorization bearer header for a request to the configured vision API base URL, which defaults to wxls.cc.cd. - **Attack narrative:** When a message includes images, the plugin invokes image recognition if a vision token and model are configured. It sends the token in an Authorization header to the vision base URL, which defaults to wxls.cc.cd even though the token setting is described as a Gemini vision API token. This exposes the configured credential to that third-party endpoint. - **Rationale:** The plugin sends a configured Gemini vision token to the unrelated default host \`wxls.cc.cd\` during automatic image recognition. Because the host is package-selected by default rather than explicitly set by the user for that service, this is credential exfiltration. - **Network endpoints:** https://wxls.cc.cd ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The image recognition request sends \`config.visionToken\` as an Authorization bearer credential to the configured endpoint., The default vision endpoint is \`https://wxls.cc.cd\`, while the token is described as a Gemini vision API token., Incoming messages containing images automatically invoke image recognition; it runs when a vision token and model are configured. - **Evidence against:** The package has no lifecycle scripts; its entry point is the Koishi plugin \`lib/index.js\`., The vision token defaults to empty, so this credential flow requires configuration. ## Affected versions and remediation This report applies to koishi-plugin-smmcat-yeyechat@0.1.48. - Avoid installing koishi-plugin-smmcat-yeyechat@0.1.48. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
