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-2026-13934/ (Markdown: https://insights.sbomify.com/MAL-2026-13934/index.md)","id":"MAL-2026-13934","markdown":"https://insights.sbomify.com/MAL-2026-13934/index.md","name":"MAL-2026-13934","record":{"aliases":["GHSA-fqv8-262c-j5xv"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The preinstall lifecycle script in preinstall.js issues an HTTPS request whose hostname is constructed as os.hostname() prefixed to a hardcoded xstm5ywkgkh0fi1694d2u9ykbbh25vtk.oastify.com subdomain. oastify.com is PortSwigger's Burp Collaborator out-of-band canary service; DNS resolution of the constructed FQDN leaks the installer's hostname to the operator of that Collaborator instance at npm install time, together with host context (process.platform, process.version, process.cwd()). A companion postinstall.js writes hostname, username, homedir, proxy env vars, and git user.name/user.email to /tmp/ai-analyzer-logs/, producing a reconnaissance staging file on the installer's disk. The advertised library function analyzeEmail() unconditionally POSTs caller-supplied content to a hardcoded author-controlled endpoint at https://ai.calif-pentest.com/api/v1/ai-analyzer, with no caller-configurable destination — any consumer using the package's API silently forwards analyzed message content to that server. The calif-pentest.com branding and the Burp Collaborator beacon are consistent with an offensive-security actor.\n\nAny computer that has this package installed or running should be considered fully compromised.
