Root Cause Analysis
- All vulnerability descriptions explicitly cite the 'set' function as the entry point
- The PoC demonstrates pollution via confucious.set('proto:polluted', ...)
- Prototype pollution typically occurs in functions that recursively merge objects or handle property paths without prototype validation
- Multiple authoritative sources (CVE, GHSA, Snyk) concur on the vulnerable function
- Lack of path sanitization for proto keys in property assignment logic matches classic prototype pollution patterns
