SCA: security update for ws (GHSA-96hv-2xvq-fx4p)

high Tenable Self-Hosted Container Security Plugin ID 443213

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-48779)

Solution

Update the ws library and its related packages to version 5.2.5 or later.
