Kerentanan Uncontrolled Recursion pada nestjs nest. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.19, when an attacker sends many small, valid JSON messages in one TCP frame, handleData() recurses once per message; the buffer shrinks each call. maxBufferSize is never reached; call stack overflows instead. A ~47 KB payload is sufficient to trigger RangeError. This vulnerability is fixed in 11.1.19.
