UBUNTU-CVE-2026-54490 (CVE-2026-54490)

Vulnerability from osv_ubuntu – Published: 2026-07-17 21:17 – Updated: 2026-07-29 07:59 – Source website

Details

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, if this library is used with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size because the limit is checked against the message frames' length headers, which give the size of the compressed data, not the size after decompression in lib/websocket/driver/hybi.js. This can lead to applications accepting larger messages than expected and exceeding their intended resource usage. This issue is fixed in version 0.7.5.
