Lockfile-only remediation; package.json is unchanged since the fix is an in-range transitive bump (cosmiconfig requires js-yaml ^4.1.0):

  • js-yaml 4.3.0 -> 4.3.1 High GHSA-5p4m-2wfm-xmqj / CVE-2026-59870 Quadratic CPU consumption in !!omap resolution: a large omap sequence triggers a linear duplicate-key scan per element, blocking the event loop (DoS). dev-only, via vite-plugin-svgr -> @svgr/core -> cosmiconfig.

Resolves SECURE-4465 / CLNP-8804.
