A bundled obfuscated patch also makes external requests and interacts with WhatsApp APIs. - **Trigger:** Launching the package's WhatsApp transport after authentication. - **Impact:** A remote operator can execute arbitrary browser-context code in an authenticated WhatsApp session and the bundled patch may expose session-associated network and messaging activity. - **Evidence paths:** dist/index.cjs, dist/transport/assets/init\_patch.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T03:22:21.391Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint fetches remote patch payloads and passes their script text to browser-page evaluation; the local injected patch contains obfuscated network and messaging-related behavior. - **Attack narrative:** At runtime, the package retrieves patch scripts from package-controlled or repository endpoints and evaluates them in the WhatsApp Web page without a visible signature or content-integrity validation. Its automatically injected local patch is intentionally obfuscated and includes external fetches, IP handling, and WhatsApp API calls. This provides a concrete remote browser-code execution channel in an authenticated messaging session. - **Rationale:** The automatic remote-script download and evaluation path is a concrete remote code execution capability. The obfuscated bundled browser payload reinforces that this is not a transparent compatibility patch mechanism. - **Files touched:** dist/index.cjs, dist/transport/assets/init\_patch.js - **Network endpoints:** https://cdn.openwa.dev/patches.json, https://raw.githubusercontent.com/open-wa/wa-automate-nodejs/master/patches.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares dist/index.cjs as its runtime entrypoint., The entrypoint fetches patch data from remote endpoints without an integrity check., Downloaded patch artifacts are evaluated in the browser page automatically., The bundled init patch is heavily obfuscated and performs external fetches while accessing an IP value and WhatsApp browser APIs. ## Affected versions and remediation This report applies to @open-wa/core@5.1.0. - Avoid installing @open-wa/core@5.1.0. 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.
