MAL-2026-4688 Malicious code in tempo-shared-modules (npm)

On npm install, the preinstall script poc.js collects host identity (hostname, username, OS/platform), network configuration (ipconfig / ip a / resolv.conf), git remote, the parent project's package.json, CI configuration files (.gitlab-ci.yml,.github/workflows, Jenkinsfile, azure-pipelines.yml), and bulk-scrapes process.env for any variable name matching TOKEN, AWS, AZURE, NPM, GITHUB, GITLAB, CI_, JENKINS, BUILD, or WALMART together with their values. The collected payload is POSTed over HTTPS to the hardcoded interactsh OAST endpoint d8a5d9pon5bugoc35cngp9hcregcqyezu.oast.me. The package is published at version 99.0.2 on the public npm registry under a name designed to be resolved by mistake instead of an internal @livingdesign/react private package — the canonical dependency-confusion shape. The package's own description self-labels it as a Walmart HackerOne PoC, but it is publicly installable and any non-Walmart installer that resolves it is harmed: their CI tokens, cloud credentials, and pipeline configuration are sent to a third-party OAST callback host. Any one of (preinstall env-credential scrape, hardcoded OAST exfil endpoint, dependency-confusion publication shape) is independently sufficient to block.
