Description

This security bulletin contains information about 1 vulnerability.


1) Uncontrolled Memory Allocation (CVE-ID: CVE-2026-19204)

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to memory allocation with an excessive size value in the Jetty WebSocket frame parser's Parser.parsePayload method when processing a WebSocket frame with a reserved opcode and an oversized declared payload length. A remote attacker can send a specially crafted WebSocket frame header to cause a denial of service.

Auto-fragmentation is enabled by default, and reserved opcodes bypass the applicable frame-size checks before opcode validation occurs.
