(#41595) ## Description Fixes a **critical** security vulnerability (CVE-2026-25896, CVSS 9.3) in `fast-xml-parser` — an entity encoding bypass via regex injection in DOCTYPE entity names that allows XSS and injection attacks when parsed XML output is rendered. This also resolves a **high-severity** DoS vulnerability (Dependabot alert #510) — DoS through entity expansion in DOCTYPE with no expansion limit. **Vulnerable range**: `>= 4.1.3, < 4.5.4` **Fix version**: `4.5.4` ### Changes - **`package.json`**: Added `"fast-xml-parser": "4.5.4"` to Yarn `resolutions` to override the transitive dependency (via `@smithy/core` → `@aws-sdk/client-s3`) - **`recommendedLibraries.ts`**: Updated CDN URL from cdnjs `4.3.2` to jsdelivr `4.5.4` (cdnjs does not yet host 4.5.4) - **`Library_spec.ts`**: Updated Cypress E2E test CDN URLs from `4.2.7` to `4.5.4` - **`yarn.lock`**: Regenerated with `fast-xml-parser@4.5.4` resolution ### Note on v3.17.5 (legacy xmlParser) The legacy `xmlParser` v3.17.5 referenced in `ApplicationConstants.java` and test fixtures is **not affected** by this CVE (vulnerable range starts at 4.1.3). It is already documented as deprecated for backward compatibility.
