Summary

CVE-2023-37899 is a vulnerability affecting Feathersjs, a popular framework for building web APIs and real-time applications. The issue lies in the Feathers socket handler, which fails to identify and handle invalid string conversion errors. Specifically, an unexpected Socket.io message, such as `socket.emit('find', { toString: '' })`, can cause the NodeJS process to crash due to the erroneous `toString: ''` conversion.

Users are strongly advised to upgrade to protect against potential crashes and potential subsequent security risks.
