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-2026-13787/ (Markdown: https://insights.sbomify.com/MAL-2026-13787/index.md)","id":"MAL-2026-13787","markdown":"https://insights.sbomify.com/MAL-2026-13787/index.md","name":"MAL-2026-13787","record":{"aliases":["GHSA-f5c6-4rpr-wjhp"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Package ships a compiled Next.js application (server routes under app/.next-cli-build/server/app/api/) implementing an LLM/AI-provider router: OAuth import flows for provider CLIs (codex, cursor, cline, kilo, droid, hermes, jcode, deepseek, opencode, openclaw, grok, devin, cowork), OpenAI-compatible endpoints (/api/v1/chat/completions, /embeddings, /images/generations, /videos/*, /responses, /messages), provider validation/testing (ping, curl), and Tailscale tunnel management. Many API route bundles include child_process, os, http/https, and process.env because Next.js server bundling co-locates these Node built-ins per route file; static keyword co-occurrence of require('child_process') + POST + process.env in minified route bundles matches the exfiltration pattern shape but reflects normal Next.js server-side rendering plus the app's documented purpose (spawn CLI tools, validate providers via ping, test provider endpoints). cli.js performs a version check against https://registry.npmjs.org (the official npm registry) and reads os.homedir() for local config. No traced code path shows installer-secret paths (~/.aws, ~/.ssh, ~/.npmrc contents) being read and sent to an author-controlled host; no lifecycle scripts fetch-and-exec remote content; no hardcoded non-registry C2 destination is confirmed in the evidence. The behavior surface (spawning CLIs, reading provider credentials that the user configures into the app, contacting external LLM providers) is consistent with the app's declared router purpose, but the density of shell-exec + network primitives across dozens of route handlers plus a MITM server module (app/src/mitm/server.js) warrants human review of the maintainer and endpoints before trust.\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 biklirouter (npm)","id":"MAL-2026-13787","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":"biklirouter","purl":"pkg:npm/biklirouter","source":"MAL-2026-13787"}],"products":null,"published":"2026-08-12","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-2026-13787/"}
