Socket.IO: Zero-attachment Memory Exhaustion
Quick fix
GHSA-2m8v-j782-fhvr — socket.io-parser: upgrade to the fixed version with the command below.
npm install socket.io-parser@4.2.7Details
### Impact
A specially crafted Socket.IO packet can make the server wait for a large number of binary attachments and buffer them, which can be exploited to make the server run out of memory.
### Patches
| Version range | Used by | Fixed version | |------------------|--------------------------------------------|---------------| | `>=4.0.0 <4.2.7` | `socket.io@4.x` and `socket.io-client@4.x` | `4.2.7` | | `>=3.4.0 <3.4.5` | `socket.io@2.x` | `3.4.5` | | `<3.3.6` | `socket.io-client@2.x` | `3.3.6` |
### Workarounds
There is no known workaround except upgrading to a safe version.
