Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected package behavior does not establish a concrete attack: its install hook sets up Jujutsu, and the reviewed credential and agent-related paths align with the product’s cloud and local tooling functions. However, the selected @xterm/headless runtime dependency is loaded by the package and its bundled source remains materially unresolved, so this review cannot certify the package as clean. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-22T03:54:10.355Z - **Finished:** 2026-10-22T03:55:17.651Z - **Download time:** 1027 ms - **Static scan time:** 2198 ms - **AI review time:** 64069 ms - **Total time:** 67296 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:** No concrete attack was identified in the inspected package paths. Review remains unresolved because a runtime-loaded terminal dependency could not be fully assessed from the bounded inspection. - **Trigger:** Use of the terminal echo predictor loads the declared terminal dependency. - **Impact:** The dependency’s remaining behavior cannot be determined from the inspected source, so a clean conclusion is not supported. - **Evidence paths:** package.json, dist/predict.js, .lpm-dependency-evidence-3487e0c3-e4a9-442f-acab-3861f4a9ebd1/0/npm-linux/lib-headless/xterm-headless.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T03:55:17.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package imports the dependency as its headless terminal model; its bundled implementation was too large to resolve fully in the available inspection. - **Rationale:** The inspected package behavior does not establish a concrete attack: its install hook sets up Jujutsu, and the reviewed credential and agent-related paths align with the product’s cloud and local tooling functions. However, the selected @xterm/headless runtime dependency is loaded by the package and its bundled source remains materially unresolved, so this review cannot certify the package as clean. - **Files touched:** package.json, dist/predict.js, .lpm-dependency-evidence-3487e0c3-e4a9-442f-acab-3861f4a9ebd1/0/npm-linux/package.json, .lpm-dependency-evidence-3487e0c3-e4a9-442f-acab-3861f4a9ebd1/0/npm-linux/lib-headless/xterm-headless.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 76.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package declares a runtime dependency on @xterm/headless, and dist/predict.js loads it when the terminal echo predictor is used., The dependency’s selected entry is a large bundled file; relevant behavior remains unresolved after the bounded source inspection., Cloud credential staging is part of explicit cloud functionality, and keychain access is attempted only when a human is at a terminal., The reviewed agent-related locations read local skills, conversation metadata, and model cache data. - **Evidence against:** The postinstall hook imports the Jujutsu setup helper and skips setup when requested or running as root., Codex usage credentials are sent to the ChatGPT usage endpoint, consistent with the quota lookup. ## Affected versions and remediation This report applies to @exla/rudder@3.9.1. - Review the evidence and your use of @exla/rudder@3.9.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
