Hi,

The following vulnerability was published for node-ws.

CVE-2026-48779[0]:
| ws is an open source WebSocket client and server for Node.js. All
| versions from 1.1.0 up to (but not including) 5.2.5, from 6.0.0 up
| to 6.2.4, from 7.0.0 up to 7.5.11, and from 8.0.0 up to 8.21.0 are
| affected by a memory exhaustion DoS vulnerability. A peer can send a
| high volume of exceptionally small fragments and data chunks, with
| modest network traffic, to force the remote peer into allocating and
| holding structural wrappers that consume far more memory than the
| default documented message-size limit, leading to process
| termination due to OOM. This issue has been fixed in versions 5.2.5,
| 6.2.4, 7.5.11, and 8.21.0.


If you fix the vulnerability please also make sure to include the
