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-2026-10136/ (Markdown: https://insights.sbomify.com/MAL-2026-10136/index.md)","id":"MAL-2026-10136","markdown":"https://insights.sbomify.com/MAL-2026-10136/index.md","name":"MAL-2026-10136","record":{"aliases":["GHSA-2j63-q9jc-966c"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"package.json declares both a dependency and a devDependency on 'transform-es2015-sticky-regex' pointing at http://pack.nppacks.com/npm/transform-es2015-sticky-regex. On `npm install`, npm fetches whatever tarball that plain-HTTP, non-registry host currently serves and installs it into node_modules with no version pin and no integrity hash — the maintainer of pack.nppacks.com can substitute arbitrary code at any time and it will land in the installer's dependency tree on the next install. The package name is also a namespace-confusion of the well-known 'babel-plugin-transform-es2015-sticky-regex' (Babel plugin naming convention prefixes 'babel-plugin-'); the shipped index.js does not implement the sticky-regex transform but a DefinePlugin-style identifier replacer, and a source comment states the package is 'for Security Research Testing Purpose'. Additional network-capable dependencies (axios, node-fetch, ws) are declared but unused by the shipped code, pre-staging network primitives for whatever the swapped tarball chooses to import.\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 transform-es2015-sticky-regex (npm)","id":"MAL-2026-10136","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":"transform-es2015-sticky-regex","purl":"pkg:npm/transform-es2015-sticky-regex","source":"MAL-2026-10136"}],"products":null,"published":"2026-07-10","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-2026-10136/"}
