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-2026-16394/ (Markdown: https://insights.sbomify.com/MAL-2026-16394/index.md)","id":"MAL-2026-16394","markdown":"https://insights.sbomify.com/MAL-2026-16394/index.md","name":"MAL-2026-16394","record":{"aliases":["GHSA-q747-c2cv-gfhj"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require() of the package's main entry and on invocation of the `dot2env` CLI, the module reads the bundled `dist/stest.jpg`, parses JPEG markers, and extracts a UTF-8 string from the APP13 (0xED) segment. The extracted string is passed as an argument to `powershell.exe -NoProfile -NonInteractive -EncodedCommand`, launched hidden on Windows via a VBS relay dropped to `%TMP%` and invoked through `wscript.exe`. The invocation is assembled from split string fragments (`['power','shell','.exe'].join('')`, `-Encoded`+`Command`, `wscript`+`.exe`) to hide the command from static scanners, and identifiers use a telemetry/analytics cover story (`telemetryFs`, `dispatchAnalytics`, `analyticsEnvelope`, `scanMetricFrame`). Execution is triggered unconditionally by a top-level `const {dispatchAnalytics:Re}=T(); Re();` in `dist/index.cjs`. The bundle also embeds a `package.json` fragment declaring `name: 'node-env-buffer', version: '2.2.6'` while the tarball is published as `envparse2@1.0.1`, indicating a renamed republish under a dotenv-style cover identity. The 287 KB JPEG has no legitimate role in a dotenv-style library; it is a container for the executable payload.\n\nAny computer that has this package installed or running should be considered fully compromised.
