Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary code execution with package consumer privileges; payload behavior is controlled by remote endpoint. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.1.8 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Static source inspection confirms an attacker-controlled remote payload loader and executor reachable at runtime. Lack of install hooks lowers automatic install-time impact, but does not mitigate confirmed malicious RCE behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-07-03T06:27:28.665Z - **Finished:** 2026-07-03T06:28:08.943Z - **Download time:** 260 ms - **Static scan time:** 60 ms - **AI review time:** 39958 ms - **Total time:** 40278 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:** Confirmed remote code execution is present. Runtime invocation of the exported middleware or import of lib/transport can fetch and execute attacker-controlled JavaScript. - **Trigger:** Calling exported middleware from index.js, or loading lib/transport.js - **Impact:** Arbitrary code execution with package consumer privileges; payload behavior is controlled by remote endpoint. - **Evidence paths:** package.json, index.js, lib/caller.js, lib/transport.js, lib/tools.js - **Review source:** ai\_review - **Reviewed:** 2026-07-03T06:28:08.943Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached child process plus remote payload fetch and Function constructor execution - **Attack narrative:** The main export looks like middleware, but calling it launches a detached Node process running lib/caller.js. That file fetches a remote JSON value from jsonkeeper.com and executes the returned \`cookie\` string as JavaScript with access to \`require\`. The same caller module is also imported by lib/transport.js, creating another runtime side-effect path. This is unconsented remote code execution, not package-aligned functionality. - **Rationale:** Static source inspection confirms an attacker-controlled remote payload loader and executor reachable at runtime. Lack of install hooks lowers automatic install-time impact, but does not mitigate confirmed malicious RCE behavior. - **Files touched:** lib/caller.js - **Network endpoints:** https://jsonkeeper.com/b/D3GLF ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js exports middleware that spawns detached \`node ./lib/caller.js\` when invoked., lib/caller.js fetches \`https://jsonkeeper.com/b/D3GLF\` with axios., lib/caller.js reads \`.data.cookie\` from the response and executes it via \`new Function.constructor("require", s)\`., lib/transport.js imports \`./caller\`, so loading that module also triggers the remote fetch/execute side effect., Package appears to copy Pino files/docs while publishing as \`webpack-patch\`, with added remote-code loader. - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle scripts., No local credential/file harvesting code is visible in inspected package source before the remote payload executes. ## Affected versions and remediation This report applies to webpack-patch@1.1.8. - Avoid installing webpack-patch@1.1.8. 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.
