🔒 Security Updates: Fix Critical Vulnerabilities in lodash-es and dompurify

Summary

This PR addresses critical security vulnerabilities identified by Snyk in two key dependencies:

• lodash-es: 4.17.23 → 4.18.1 (fixes 2 critical issues)
• dompurify: 3.3.3 → 3.4.0 (fixes 1 medium severity issue)

🚨 Security Issues Resolved

lodash-es (Risk Score: 240 - HIGH)

• CVE-2026-4800: Arbitrary Code Injection via _.template imports (CVSS 8.6)
• CWE-1321: Prototype Pollution via _.unset/_.omit (CVSS 6.9)

dompurify (Risk Score: 104 - MEDIUM)

• CWE-783: Operator Precedence Logic Error (CVSS 6.3)
• Multiple mXSS vulnerabilities and configuration handling improvements

✅ Safety Assessment

SAFE TO DEPLOY - No Breaking Changes Affect Our Codebase

After thorough analysis of our codebase usage patterns:

lodash-es Usage Analysis

Our codebase uses these safe lodash-es functions:

// ✅ SAFE - Not affected by security changes
import { 
  isNil, isFinite, findLastIndex, findLast,    // cslp/cslpdata.ts
  startCase, toLower,                          // emptyBlock.tsx  
  debounce, isEqual,                          // multiple files
  uniqBy,                                     // fieldLabelWrapper.tsx
  has, set,                                   // configManager.ts
  cloneDeep, isEmpty, pick,                   // contentstack-live-preview-HOC.ts
  throttle, camelCase, findIndex              // various utils
} from "lodash-es";

🔍 Potentially Affected Functions (NOT USED in our codebase):

• _.unset() - ❌ Not found in codebase
• _.omit() - ❌ Not found in codebase
• _.template() - ❌ Not found in codebase

dompurify Usage Analysis

Our codebase has minimal, safe usage:

// ✅ SAFE - Standard usage pattern, enhanced security
export const sanitizeData = (dirty: any): string => {
    return DOMPurify.sanitize(dirty, { USE_PROFILES: { html: true } });
};

🔍 Enhanced Security: The USE_PROFILES configuration we use is now more secure against prototype pollution.

🧪 Testing Results

• ✅ All 748 tests passed (105 test files)
• ✅ 70.97s execution time - no performance regression
• ✅ No functionality changes detected
• ✅ Core Live Preview functionality verified

📊 Risk Assessment

Component	Breaking Risk	Our Usage	Impact
lodash-es	🟢 None	Safe functions only	✅ Zero impact
dompurify	🟢 None	Standard config	✅ Enhanced security

🔄 What Changed

lodash-es 4.18.1

• Security Enhancement: Prevents prototype pollution in _.unset()/_.omit()
• Security Enhancement: Validates _.template() imports for code injection
• Bug Fix: Resolves ReferenceError in modular builds

dompurify 3.4.0

• Security Enhancement: FORBID_TAGS now properly overrides ADD_TAGS
• Security Enhancement: Fixed prototype pollution via custom element handling
• Security Enhancement: Stricter URI validation for custom attributes
• Bug Fix: Prevents function leaking between sanitization calls

🚀 Deployment Recommendation

IMMEDIATE DEPLOYMENT RECOMMENDED

This is a security-critical update with:

• ✅ Zero breaking changes for our codebase
• ✅ All tests passing
• ✅ Enhanced security posture
• ✅ No functional regressions

📝 Additional Notes

• Production Monitoring: No special monitoring required - standard usage patterns unaffected
• Future Considerations: These updates make our SDK more secure against XSS and prototype pollution attacks
• Developer Impact: Zero impact on existing integrations and developer workflows

LGTM...merge it to develop_v4 and get it tested on dev22 with all the three features: live preview, timeline and visual builder
