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 this package launches a detached daemon that downloads and executes code chosen by the remote signing-key holder. The signature check does not constrain what that authorized server may execute. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-09T23:55:47.927Z - **Finished:** 2026-09-09T23:56:33.358Z - **Download time:** 514 ms - **Static scan time:** 53 ms - **AI review time:** 44864 ms - **Total time:** 45431 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 this package launches a detached daemon that downloads and executes code chosen by the remote signing-key holder. The signature check does not constrain what that authorized server may execute. - **Trigger:** Requiring the package at runtime. - **Impact:** The remote server can run arbitrary Node.js code in the importing application's environment. - **Evidence paths:** index.js, lib/check-items.js, SECURITY\_SETUP.md - **Review source:** ai\_review - **Reviewed:** 2026-09-09T23:56:33.358Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote signed-payload download followed by dynamic execution. - **Attack narrative:** When an application imports the package, index.js spawns a detached Node process. That process downloads a code string from game.spawnrealm.com and, after verifying a signature controlled by the package publisher's server, executes it through Function with access to require. This gives the remote signing-key holder a post-publication path to run arbitrary code in each importing application's environment without publishing a new package version. - **Rationale:** This is concrete remote code execution activated by a normal import, not merely a validator. The signing gate authenticates the publisher-controlled remote payload but does not make its arbitrary execution 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 main module automatically starts a detached child process., The child fetches a signed code payload from a hard-coded external server., After signature verification, the package executes server-provided text with Node's require available., The bundled security guide attempts to reassure scanners and claims there is no malware risk, which is reviewer-directed social engineering. - **Evidence against:** package.json contains no npm lifecycle scripts., The remote payload must pass an RSA signature check before execution. ## Affected versions and remediation This report applies to open-item-validator@1.0.4. - Avoid installing open-item-validator@1.0.4. 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.
