fix: resolve fast-xml-parser HIGH/CRITICAL vulnerabilities#3477
Conversation
…ties Upgrades AWS SDK client packages and adds a resolution to eliminate vulnerable fast-xml-parser versions (4.4.1, 5.2.5, 5.5.2) from the dependency tree. Changes: - Broadened fast-xml-parser resolution to force all instances to ~5.5.12 - Updated @aws-sdk/core, @aws-sdk/xml-builder and related packages in amplify-data-construct and amplify-graphql-api-construct - Upgraded direct fast-xml-parser dep from 5.5.2 to ~5.5.12 in constructs - Upgraded AWS SDK clients in test packages to ^3.973.0 After these changes, yarn.lock contains only fast-xml-parser@5.5.12 (safe, >= 5.5.6) with no vulnerable versions remaining.
Remove stale lockfile entries for @aws-sdk packages in the 3.775.x and 3.810.x version families that declared fast-xml-parser 4.4.1. These came from aws-appsync@4.1.10 (via @aws-sdk/client-s3@^3.25.0 resolved to 3.779.0) and @aws-cdk/toolkit-lib@1.16.0 (via @aws-sdk/client-*@^3 resolved to 3.810.0). After removal, yarn install re-resolved these ranges to the latest compatible versions which use @aws-sdk/core >= 3.974.8 (no fast-xml-parser dependency). Remaining: @aws-sdk/core@3.622.0 from @aws-amplify/ai-constructs@1.6.1 still declares fast-xml-parser 4.4.1, but the resolution forces it to 5.5.12. This will be addressed separately.
