Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Static source inspection found a concrete shell command-injection risk in video thumbnail generation. The install hook and the other reviewed flagged code do not establish malicious package behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-09T03:19:18.510Z - **Finished:** 2026-10-09T03:19:49.133Z - **Download time:** 515 ms - **Static scan time:** 1487 ms - **AI review time:** 28620 ms - **Total time:** 30623 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 exported video thumbnail helper interpolates its file path into a shell command. An attacker-controlled path can therefore affect shell execution when the caller requests video thumbnail generation. - **Trigger:** A caller invokes video thumbnail generation with a path controlled by untrusted input. - **Impact:** Shell metacharacters in the supplied path may execute unintended commands with the package process's privileges. - **Evidence paths:** lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T03:19:49.133Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper builds an ffmpeg command by interpolating path values and executes it through child\_process.exec. - **Rationale:** Static source inspection found a concrete shell command-injection risk in video thumbnail generation. The install hook and the other reviewed flagged code do not establish malicious package behavior. ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The exported thumbnail helper passes its file argument into a shell command without escaping it, creating a command-injection risk when callers supply an attacker-controlled path., The video thumbnail path calls that helper with its supplied file argument., The preinstall hook only checks the Node.js version; no malicious install behavior was identified., The flagged network code fetches caller-supplied URLs and uploads media through a WhatsApp media upload helper., The flagged constant is one entry in a binary protocol token table., The business helper uploads product images through a supplied WhatsApp upload callback. - **Evidence against:** The package manifest has empty prepare and prepack hooks, and its preinstall script invokes a Node-version requirement check., The inspected network and media paths align with WhatsApp media handling; no credential harvesting or unrelated exfiltration was identified. ## Affected versions and remediation This report applies to @badzz88/baileys@8.4.7. - Review the evidence and your use of @badzz88/baileys@8.4.7 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.
