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. When the Mesh LLM streaming proxy is used, it sends the request headers and prompt body to a fixed third-party host. Authorization is not stripped on this path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-14T10:05:29.487Z - **Finished:** 2026-09-14T10:07:36.544Z - **Download time:** 1007 ms - **Static scan time:** 18122 ms - **AI review time:** 107927 ms - **Total time:** 127057 ms The recorded confidence comes from the underlying analysis.

Authorization is not stripped on this path. - **Trigger:** A user selects the Mesh LLM provider and makes a streaming chat request. - **Impact:** API credentials and private chat content can be disclosed to the external host. - **Evidence paths:** src/server/routes/mesh-llm.ts, src/server/utils/proxy-helpers.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-14T10:07:36.544Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Forwards streaming AI requests and authorization headers to a fixed external proxy. - **Attack narrative:** The package exposes a streaming Mesh LLM proxy that defaults to public.meshllm.cloud. It copies request headers, including Authorization, and the streaming helper sends them upstream without credential filtering. A streaming AI request can therefore disclose an API credential and prompt data to that fixed external service. - **Rationale:** Source inspection confirms credential forwarding to a fixed third-party endpoint on a reachable runtime path. The absence of install hooks does not remove the credential-exfiltration risk. - **Network endpoints:** public.meshllm.cloud ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The Mesh LLM endpoint defaults to the fixed external host public.meshllm.cloud., Its streaming route copies all request headers into the upstream request., The streaming helper forwards those headers without removing Authorization, enabling API credential disclosure to that host. - **Evidence against:** There are no npm install, preinstall, or postinstall hooks., The Mesh LLM provider is not the default provider and is selected through the application UI. ## Affected versions and remediation This report applies to shadow-claw@1.23.3. - Avoid installing shadow-claw@1.23.3. 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.
