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-2026-18200/ (Markdown: https://insights.sbomify.com/MAL-2026-18200/index.md)","id":"MAL-2026-18200","markdown":"https://insights.sbomify.com/MAL-2026-18200/index.md","name":"MAL-2026-18200","record":{"aliases":["GHSA-fv2r-964m-pc2m"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package ships a bundled UI asset at dist/ui/app.js in which the token 'ping' appears multiple times on a single minified line. No code path reads installer secrets, environment variables, or filesystem contents, and no outbound network call to an attacker-controlled destination is present. The keyword co-occurrence matched by the rule is consistent with ordinary bundled UI code (e.g., WebSocket keep-alive 'ping'/'pong' messages or similar UI logic) rather than a command-execution or exfiltration path. No install-time or import-time side effects, no lifecycle scripts fetching remote content, and no credential-handling behavior were observed.\n\nAny computer that has this package installed or running should be considered fully compromised.
