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-2026-14288/ (Markdown: https://insights.sbomify.com/MAL-2026-14288/index.md)","id":"MAL-2026-14288","markdown":"https://insights.sbomify.com/MAL-2026-14288/index.md","name":"MAL-2026-14288","record":{"aliases":["GHSA-p4gf-f4rj-hfh8"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"dist/index.js of @wizloft/harness-plugin-repository-files ships a small legitimate wizloft-harness repository-files plugin followed at line 209 by a ~35KB obfuscator.io-packed IIFE (303-entry rotated string array _0x240a with decoder _0x4963, control-flow flattening, hex-named identifiers). Decoded strings in the appended segment include Ethereum JSON-RPC and block-explorer endpoints (drpc.org, publicnode.com, blockscout, an etherscan-style txlist/account API), a hardcoded mixed-case ETH address prefix 0xa322E5f3..., a forged Chrome User-Agent, brotli/gzip decompression, AbortController-based fetch, and a custom /0x/ls exfil path with x-payload-* headers. The payload runs at module load whenever a consumer imports the package and has no relationship to the advertised purpose of reading repository files for a harness runtime. Only the trailing segment is obfuscated; the legitimate plugin portion is plain ESM, indicating a hostile payload smuggled onto an otherwise-clean plugin build.\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.
