…solution Forces cosmiconfig to ^8.0.0 via yarn resolutions, replacing yaml@1.10.2 (SNYK-JS-YAML-15765520) with js-yaml@4 in the babel-plugin-macros dependency chain. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds js-yaml resolution alongside the cosmiconfig upgrade; cosmiconfig@8 pulls in js-yaml@4.1.0 which has SNYK-JS-JSYAML-13961110 (CVE-2025-64718). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
v9 is the current stable release; ^8.0.0 was unnecessarily conservative. Both eliminate yaml@1.10.2 and the API used by babel-plugin-macros is unchanged. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Added two Yarn
resolutionsentries inpackage.json:"cosmiconfig": "^8.0.0"— upgrades cosmiconfig from v7 to v8, which switches from the vulnerableyaml@1.10.2tojs-yaml. Chain:@emotion/react/@emotion/styled → @emotion/babel-plugin → babel-plugin-macros → cosmiconfig@7 → yaml@1.10.2."js-yaml": ">=4.1.1"— cosmiconfig@8 depends onjs-yaml@4.1.0which has Prototype Pollution; this resolution pins it to the patched4.1.1.Strategy (SCA)
Strategy D — Yarn
resolutionsoverride. Breakability risk: low — cosmiconfig v7→v8 is API-compatible; js-yaml 4.1.1 is a patch-only bump.Validation
