Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-13390/ (Markdown: https://insights.sbomify.com/MAL-2026-13390/index.md)","id":"MAL-2026-13390","markdown":"https://insights.sbomify.com/MAL-2026-13390/index.md","name":"MAL-2026-13390","record":{"aliases":["GHSA-fj9m-r2qx-cc39"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Package is a fork of the Baileys WhatsApp Web library. Static keyword co-occurrence patterns matched on lib/Utils/generics.js (ping/GET references) and lib/Utils/messages-media.js (require('child_process') alongside POST/GET/hostname tokens), but these are consistent with Baileys' normal media upload/download paths and connectivity checks rather than a traced exfiltration flow. The concern is fork provenance: Baileys forks have previously been used to wire covert side effects (e.g. auto-follow of author-controlled newsletters, install counters) into the main exported API using the consumer's authenticated WhatsApp session. No specific installer-side data read and non-first-party destination pair has been identified in the code paths matched.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
