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-2026-14286/ (Markdown: https://insights.sbomify.com/MAL-2026-14286/index.md)","id":"MAL-2026-14286","markdown":"https://insights.sbomify.com/MAL-2026-14286/index.md","name":"MAL-2026-14286","record":{"aliases":["GHSA-wjhv-xmmw-qqf9"],"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 (the package's declared main) contains a heavily obfuscated obfuscator.io-style IIFE appended after the legitimate context-service code. On import, the payload stashes `global.r = require` and `global.m = module`, then issues HTTPS requests to an Ethereum public RPC endpoint (h.drpc.org) and a block-explorer account API to read state from contract 0xa322E5f3..., using that state to resolve a next-stage URL that is fetched and executed in-process. The obfuscated string array (~303 entries via a rotated decoder) hides `drpc.org`, `?module=ac`, `POST`, `application/json`, `Mozilla/5.`, and the contract address. This is the EtherHiding loader pattern: attacker-controlled contract state serves as a mutable pointer to arbitrary code executed in the installer/consumer process at require time. Behavior does not match the package's advertised purpose of a small typed capability contract.\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 @wizloft/harness-context (npm)","id":"MAL-2026-14286","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":"@wizloft/harness-context","purl":"pkg:npm/%40wizloft/harness-context","source":"MAL-2026-14286"}],"products":null,"published":"2026-08-19","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-2026-14286/"}
