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-2026-12471/ (Markdown: https://insights.sbomify.com/MAL-2026-12471/index.md)","id":"MAL-2026-12471","markdown":"https://insights.sbomify.com/MAL-2026-12471/index.md","name":"MAL-2026-12471","record":{"aliases":["GHSA-vv6v-hc8c-p5q9"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"index.mjs contains an `indexCache` array of base64 string chunks whose decoded bytes begin with the ELF magic and reference `/lib64/ld-linux-x86-64.so.2`. At module load time, a top-level call to `maintainLocalIndex()` joins and base64-decodes the array, writes the resulting Linux ELF binary to a temp path, and executes it via `child_process.spawn`. Any consumer that imports `streak-view-core` runs this native binary on their host. The package presents itself as a dependency-free calendar-day/streak math utility, which does not justify shipping or self-executing a native ELF, and the payload is fragmented across many string literals to obscure the ELF header from casual review.\n\nAny computer that has this package installed or running should be considered fully compromised.
