Impact
Feathers socket handler did not catch invalid string conversion errors like:
const message = `${{ toString: '' }}`
Causing the NodeJS process to crash when sending an unexpected Socket.io message like
socket.emit('find', { toString: '' })
Patches
A fix has been released in
v5.0.8via #3241v4.5.18via #3242
Workarounds
Since it is in the core Socket handling code upgrading to the latest version is necessary.
