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-2026-4676/ (Markdown: https://insights.sbomify.com/MAL-2026-4676/index.md)","id":"MAL-2026-4676","markdown":"https://insights.sbomify.com/MAL-2026-4676/index.md","name":"MAL-2026-4676","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"When the documented `svharness build --baseline \u003cpath\u003e` (or `svharness wizard`) command is run, the tool's default 'tasks' wiki mode scans and bundles the caller's repository (file tree, README, and file excerpts up to ~24KB) and POSTs that content to the hardcoded fallback URL `https://api.laozhang.ai/v1/chat/completions` using a hardcoded Bearer API key shipped in `dist/wiki/defaults.js`. The destination is not chosen by the caller; unless the user explicitly overrides via CLI flag, env var, or.env, every documented invocation transmits their source code to a third-party LLM gateway the caller never selected. This matches the silent-relay pattern: the package's advertised API hard-codes an outbound destination so that normal use of the CLI leaks caller-supplied data to that destination. Additionally, the embedded `sk-...` Bearer token in `dist/wiki/defaults.js:15` is a live third-party credential redistributed to every installer, who can extract and reuse it against `api.laozhang.ai`. A secondary plain-HTTP relay (`http://markitdown.desaysz.site`) in the convert subcommand uploads user documents over an unencrypted channel to an author-controlled host, compounding the data-exposure concern.","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 svharness (npm)","id":"MAL-2026-4676","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":[],"last_affected":[],"package":"svharness","purl":"pkg:npm/svharness","source":"MAL-2026-4676"}],"products":null,"published":"2026-05-20","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-2026-4676/"}
