Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the module creates a detached daemon that downloads and executes code selected by the package operator. A signature gate does not constrain what the signing server may run. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T12:32:06.886Z - **Finished:** 2026-09-08T12:32:44.362Z - **Download time:** 507 ms - **Static scan time:** 45 ms - **AI review time:** 36923 ms - **Total time:** 37476 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:** Importing the module creates a detached daemon that downloads and executes code selected by the package operator. A signature gate does not constrain what the signing server may run. - **Trigger:** A consumer requires the package. - **Impact:** The remote server can run arbitrary Node.js code in the consumer environment when the module is imported. - **Evidence paths:** index.js, lib/check-items.js, SECURITY\_SETUP.md - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:32:44.362Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote payload download followed by Function execution. - **Attack narrative:** When a consumer imports the main entry point, it spawns a detached Node daemon. The daemon requests a payload from the package-controlled endpoint, checks a signature whose trusted public key is bundled by the package, then passes the returned text to Function with require access. The package operator, or anyone controlling its signing key and server, can therefore deliver arbitrary code without a package update. Documentation also attempts to frame this remote execution mechanism as scanner-compliant and risk-free. - **Rationale:** This is concrete remote code execution on import from a hard-coded package-controlled endpoint. Signature verification authenticates the operator's payload but does not make arbitrary remotely delivered Node code safe. - **Files touched:** index.js, lib/check-items.js - **Network endpoints:** https://game.spawnrealm.com/api/item-realtime?key=abc123def456 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Importing the package automatically starts a detached background Node process., The daemon fetches JavaScript from a hard-coded remote endpoint., The fetched server-controlled code is executed with Node's require capability through Function., Package documentation addresses scanner classification and asserts that signed code has no malware risk. - **Evidence against:** The manifest has no install lifecycle scripts or dependencies., The daemon verifies an RSA signature before executing the downloaded payload., No local file harvesting, credential collection, or file modification is present in the inspected runtime source. ## Affected versions and remediation This report applies to open-item-validator@1.0.5. - Avoid installing open-item-validator@1.0.5. 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.
