CVE-2026-0716 (opens in a new tab)How to fix?
Upgrade libsoup to version 3.6.6 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Access with Incorrect Length Value in the WebSocket frame processing when the max_incoming_payload_size is set to 0 or left unset. An attacker can cause memory disclosure or application instability by sending specially crafted WebSocket frames. This is only exploitable if the max_incoming_payload_size is explicitly set to 0 or is unset in the configuration.
Workaround
This vulnerability can be mitigated by configuring the max_incoming_payload_size parameter to a non-zero value in applications utilizing WebSocket support.
