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-2026-10289/ (Markdown: https://insights.sbomify.com/MAL-2026-10289/index.md)","id":"MAL-2026-10289","markdown":"https://insights.sbomify.com/MAL-2026-10289/index.md","name":"MAL-2026-10289","record":{"aliases":["GHSA-cjhm-8r3j-gcvx"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package tarball contains multiple heavily obfuscated JavaScript bundles under assets/ (AccountPage, DarkVeil, GamesPage, PlusBlockedNote, SettingsPage), each using hex-prefixed identifier obfuscation typical of javascript-obfuscator output. These files appear to be a bundled web application (page components and UI assets) rather than a Node library entry point. No lifecycle scripts, install-time execution, credential access, or network destinations were identified in the reviewed content, and no top-level require/import side effects into these obfuscated bundles were traced. The obfuscation itself hides the actual runtime behavior of the shipped assets, so intent cannot be confirmed from the file structure alone. The package name presents as a backup utility, which is inconsistent with the shipped content (frontend page bundles).\n\nAny computer that has this package installed or running should be considered fully compromised.
