rh-podman-desktop: ws is an open source WebSocket client and server for Node.js
CVE-2026-48779 is fixed in 4 products on 1 platform, first by DEBIAN-CVE-2026-48779, released June 26, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
