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 package has a conditional relay path that forwards configured provider credentials and prompts to api.aicodemirror.ai for specific model IDs. Because this requires choosing a matching model and the default configuration uses a different provider/model path, this is a serious but conditional credential-handling risk rather than established automatic exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T02:52:22.344Z - **Finished:** 2026-11-02T02:53:01.357Z - **Download time:** 518 ms - **Static scan time:** 1099 ms - **AI review time:** 37395 ms - **Total time:** 39013 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 configured model path can send a provider API credential and prompts to a third-party relay. - **Trigger:** A user configures a matching provider and one of the hard-coded relay model IDs, then makes an LLM request. - **Impact:** The relay receives the provider credential and prompt content, creating risk of credential exposure and access to the provider account. - **Evidence paths:** dist/llm.js, dist/llm-runtime.js, dist/config.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T02:53:01.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Model resolution overrides the provider model's base URL to api.aicodemirror.ai; the LLM runtime supplies the configured provider credential to that request. - **Rationale:** The package has a conditional relay path that forwards configured provider credentials and prompts to api.aicodemirror.ai for specific model IDs. Because this requires choosing a matching model and the default configuration uses a different provider/model path, this is a serious but conditional credential-handling risk rather than established automatic exfiltration. - **Files touched:** dist/llm.js, dist/llm-runtime.js, dist/config.js - **Network endpoints:** api.aicodemirror.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** For a small hard-coded set of model IDs, resolveModel routes Anthropic, OpenAI, or Google requests through the AICodeMirror relay., The LLM runtime resolves the configured provider credential and passes it to the completion request using that model., The configured request includes the user prompt and system prompt, so the relay receives them along with the provider credential. - **Evidence against:** The default configuration uses OpenRouter with deepseek/deepseek-v4-flash; it does not select a relay model by default., The relay path is conditional on the configured provider and an exact model ID match., The manifest declares no install, preinstall, or postinstall hook; its prepublishOnly script runs tests and an audit. ## Affected versions and remediation This report applies to caitlyn@0.7.0. - Review the evidence and your use of caitlyn@0.7.0 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.
