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-2026-16254/ (Markdown: https://insights.sbomify.com/MAL-2026-16254/index.md)","id":"MAL-2026-16254","markdown":"https://insights.sbomify.com/MAL-2026-16254/index.md","name":"MAL-2026-16254","record":{"aliases":["GHSA-fwr5-cj49-cq4h"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"index.js contains top-level code that fetches /profile and sends document.cookie together with the response body to a hardcoded webhook.site URL (https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38) via a GET request with the cookie and profile content passed as URL-encoded query parameters.
