Nest Affected by DoS via Recursive handleData in JsonSocket (TCP Transport)
Quick fix
GHSA-hpwf-8g29-85qm — @nestjs/microservices: upgrade to the fixed version with the command below.
npm install @nestjs/microservices@11.1.19Details
### Impact Attacker sends many small, valid JSON messages in one TCP frame → handleData() recurses once per message; buffer shrinks each call → maxBufferSize is never reached; call stack overflows instead → A ~47 KB payload is sufficient to trigger RangeError
### Patches
Fixed in `@nestjs/microservices@11.1.19`
