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. A public media utility can invoke a shell command with unquoted caller-controlled file-path arguments. No malicious install-time attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-22T02:25:59.075Z - **Finished:** 2026-09-22T02:26:49.419Z - **Download time:** 770 ms - **Static scan time:** 1496 ms - **AI review time:** 48077 ms - **Total time:** 50344 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:** A public media utility can invoke a shell command with unquoted caller-controlled file-path arguments. No malicious install-time attack was identified. - **Trigger:** A consumer calls the exported video thumbnail generation path with a video file path containing shell metacharacters. - **Impact:** An attacker able to control the supplied path could execute commands with the consuming process's privileges. - **Evidence paths:** lib/Utils/messages-media.js, lib/Utils/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T02:26:49.419Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper interpolates path and destination values into an ffmpeg command string and passes that string to exec. - **Rationale:** The unquoted exec command is a critical, externally triggerable command-injection risk. The inspected lifecycle hook is only a Node version check and no separate malware behavior was found. ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** The package entry point exports its utility API, including the media helpers., The video-thumbnail helper builds a shell command by interpolating its path and destination arguments, then executes it with child\_process.exec., The install hook only checks the Node.js major version., The inspected business helper writes user media to a temporary file and removes it after upload., The inspected binary constants contain WhatsApp URLs rather than an operator-controlled endpoint. - **Evidence against:** No credential harvesting, secret exfiltration, persistence, or unrelated network endpoint was identified in the inspected paths. ## Affected versions and remediation This report applies to @lekzo/baileys@0.0.8. - Review the evidence and your use of @lekzo/baileys@0.0.8 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.
