Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The remote server can supply code that runs during installation with the installer's privileges. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 17.6.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 lifecycle chain executes remotely supplied JavaScript during installation, establishing a concrete install-time attack surface. The downloaded installer itself is absent from the snapshot, so its behavior cannot be assessed here; the remote execution mechanism is directly visible in source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-09T20:07:46.702Z - **Finished:** 2026-10-09T20:08:07.627Z - **Download time:** 520 ms - **Static scan time:** 18 ms - **AI review time:** 20386 ms - **Total time:** 20925 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:** The install hook retrieves remote JavaScript and the same hook chain executes it as an installer. - **Trigger:** Package installation invokes the postinstall lifecycle. - **Impact:** The remote server can supply code that runs during installation with the installer's privileges. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:08:07.627Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The first command fetches and writes remote response text to scripts/installer.js; the next command executes that file with Node.js. - **Attack narrative:** During package installation, the postinstall lifecycle downloads JavaScript from premium.rxdb.info, writes it to scripts/installer.js, and then runs that file. This creates an install-time remote code execution path controlled by the endpoint response. - **Rationale:** The lifecycle chain executes remotely supplied JavaScript during installation, establishing a concrete install-time attack surface. The downloaded installer itself is absent from the snapshot, so its behavior cannot be assessed here; the remote execution mechanism is directly visible in source. - **Files touched:** scripts/installer.js - **Network endpoints:** https://premium.rxdb.info/scripts/installer.js ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs a postinstall downloader and then executes the downloaded installer., scripts/postinstall.js fetches installer code from premium.rxdb.info and writes it into the package directory for execution. - **Evidence against:** The manifest identifies the package as RxDB Premium and links it to the RxDB project. ## Affected versions and remediation This report applies to rxdb-premium@17.6.0. - Avoid installing rxdb-premium@17.6.0. 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.
