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-2026-6925/ (Markdown: https://insights.sbomify.com/MAL-2026-6925/index.md)","id":"MAL-2026-6925","markdown":"https://insights.sbomify.com/MAL-2026-6925/index.md","name":"MAL-2026-6925","record":{"aliases":["GHSA-rff8-755c-wqvw"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"typescript-base58@1.0.0 is a one-line re-export of the 'base58-core' package. The README advertises 'Zero dependencies' while package.json declares a runtime dependency on base58-core (^1.0.0), so installing this package silently introduces base58-core into the installer's dependency tree under a misleading description. The shim itself performs no install-time or import-time actions beyond the re-export; it contains no lifecycle scripts, no network calls, no credential reads, and no obfuscation. The installer-side risk is entirely contingent on the contents of base58-core, which is not analyzed in this record.\n\nAny computer that has this package installed or running should be considered fully compromised.
