High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The npm preinstall lifecycle script (dist/scripts/preinstall.js, wired via package.json "preinstall": "node./dist/scripts/preinstall.js") reads the installer's ~/.gitconfig via iniparser.parseSync(home\_dir+'/.gitconfig') and the OS username via os.userInfo().username, then issues an HTTPS GET to the hardcoded endpoint https://2tak.l.serverhost.name:1962/mobile/reext with osname, gitname, and gitemail supplied as query parameters. The code explicitly branches on \`if (osname === 'xmarcgusmano') { server = 'http://localhost:1962' } else { server = 'https://2tak.l.serverhost.name:1962' }\`, confirming that the remote-host path fires for every installer that is not the author's own machine — a deliberate exfiltration path gated by the author's own username. The destination is not a documented vendor endpoint; it is an author-controlled third-party host the installer did not opt into. Separately, dist/scripts/postinstall.js resolves \`path.resolve(\_\_dirname, '../../package.json')\` (the consuming project's own package.json relative to node\_modules/@gusmano/reext/dist/scripts/) and rewrites it, deleting scripts.dev/build/test/watch/coverage, the entire \`scripts\` key, \`eslintConfig\`, \`devDependencies\`, and \`dependencies\`, then rm -rf's several dist subfolders — destructive, unauthorized mutation of the installer's project files. The combination (silent install-time exfiltration of personal identity data to an author-controlled host plus destructive rewrite of the consumer's manifest) is unambiguously harmful to installers. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** preinstall - **Dependencies:** 4 - **Optional dependencies:** 0 - **Peer dependencies:** 2 - **Development dependencies:** 15 - **Published dependency-graph edges:** 6 ### Published dependency entries - git-user-email ^0.2.2 (Dependency) - git-user-name ^2.0.0 (Dependency) - iniparser ^1.0.5 (Dependency) - parse-git-config ^3.0.0 (Dependency) - react \>=18.2.0 (PeerDependency) - react-dom \>=18.2.0 (PeerDependency) ## Package metadata - **Package:** @gusmano/reext - **Ecosystem:** npm - **Version:** 0.0.98 - **License:** MIT - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 34 - **Latest version:** 0.0.98 - **Appeal under review:** No - **Description:** React ReExt provides React components for the \Sencha ExtJS Framework\. - **Deprecated:** Package no longer supported.
