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. At runtime, a supplied video file path is interpolated into a shell command for ffmpeg without quoting. This creates a command-injection risk for applications that expose that argument to untrusted input. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-15T18:20:49.916Z - **Finished:** 2026-09-15T18:22:32.073Z - **Download time:** 1019 ms - **Static scan time:** 1520 ms - **AI review time:** 99617 ms - **Total time:** 102157 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:** At runtime, a supplied video file path is interpolated into a shell command for ffmpeg without quoting. This creates a command-injection risk for applications that expose that argument to untrusted input. - **Trigger:** An application calls the video thumbnail function with an attacker-controlled file path. - **Impact:** Commands may run with the privileges of the application using this library. - **Evidence paths:** lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T18:22:32.073Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unquoted shell interpolation passed to child\_process.exec. - **Rationale:** The inspected source does not establish malware or install-time compromise, but it does establish a potentially exploitable shell command injection in a public runtime media path. Downgrade pending remediation or confirmation that inputs are strictly trusted. ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** A video-thumbnail helper builds a shell command with an unquoted caller-supplied path and runs it through child\_process.exec., The package runs a preinstall script automatically, though the inspected script only checks the Node.js major version., The product-image helper writes supplied media to a temporary file and passes that path to an upload callback., The protocol constants contain WhatsApp OTP URL strings; this explains the scanner's secret-like match but is not a credential. - **Evidence against:** The preinstall script only rejects Node.js versions below 20 and performs no file, network, or configuration mutation., No credential harvesting, environment-variable collection, self-dependency, opaque payload loading, or fixed exfiltration endpoint was found in the inspected source., Network and upload helpers are runtime WhatsApp media functionality, not install-time behavior. ## Affected versions and remediation This report applies to @lekzo/baileys@0.0.2. - Review the evidence and your use of @lekzo/baileys@0.0.2 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.
