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-2026-13566/ (Markdown: https://insights.sbomify.com/MAL-2026-13566/index.md)","id":"MAL-2026-13566","markdown":"https://insights.sbomify.com/MAL-2026-13566/index.md","name":"MAL-2026-13566","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require(), dolyame-ui-deprecatepropshoc@35.8.1 side-effect-loads _adapter.js and lib/telemetry.js, which assemble Cloudflare Workers hostnames from split-string fragments (['oob-worker.cf101-adf.','wor','kers.dev'].join('')) with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru, fetch a platform-specific opaque binary (/pkg/package, /pkg/loader_mac, /pkg/package.exe), write it to /var/tmp/.cache_\u003cuid\u003e or %TEMP%\\dotnet_diag_\u003cuid\u003e.exe, apply mode 0755 via fs['chmod'+'Sync'], and spawn it detached through /bin/sh -c or cmd.exe /c start /b. child_process is loaded via require('child_'+'process') to evade static matching.
