Process crash via unvalidated socket service path
Published Jul 19, 2023 · Updated Oct 28, 2024
Denial of service in FeathersJS Feathers before 4.5.18 and 5.0.0 through 5.0.7 allows remote attackers to crash Node.js via Socket.io. The socket dispatcher interpolates an attacker-controlled service path into a debug template before validating that the path is a string, so a non-callable toString property throws an uncaught conversion error. Any unauthenticated client able to emit a service method with the crafted path can terminate the hosting process, interrupting every API and real-time service in that process.
