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-2026-10488/ (Markdown: https://insights.sbomify.com/MAL-2026-10488/index.md)","id":"MAL-2026-10488","markdown":"https://insights.sbomify.com/MAL-2026-10488/index.md","name":"MAL-2026-10488","record":{"aliases":["GHSA-9499-pgrg-v7w7"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require, index.js spawns a worker that uses koffi FFI to load a file named index.html and invoke its exported vserver_start(). Despite the extension, index.html is an aarch64 Linux ELF shared library built from vless_ws.c; it implements a VLESS-over-WebSocket proxy with a hardcoded client UUID 4916e0f5-8abc-4ad4-ba5d-158582c60d85, accepts WebSocket upgrades, and relays arbitrary attacker-directed TCP CONNECT traffic through the installing host. The ELF returns a decoy ':: SYSTEM ONLINE:: MINECRAFT SERVER' HTML page to casual HTTP probes as a cover story. One second after the worker signals 'started', index.js recursively deletes the installed package directory with fs.rmSync(pkgDir, { recursive: true, force: true }), while the loaded native library keeps running in memory. The combination of native ELF masquerading as HTML, FFI load on require, hardcoded VLESS identity, TCP relay capability, and post-activation self-deletion converts the installing host into a covert attacker-controlled proxy relay.\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. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in permcarmserver (npm)","id":"MAL-2026-10488","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"permcarmserver","purl":"pkg:npm/permcarmserver","source":"MAL-2026-10488"}],"products":null,"published":"2026-07-13","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-10488/"}
