Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-50560)

CWE-ID: CWE-400 - Resource exhaustion

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 improper handling of SETTINGS_MAX_HEADER_LIST_SIZE in the netty http/2 codec when processing http/2 requests with a client-supplied maximum header list size setting. A remote attacker can send specially crafted http/2 requests to cause a denial of service.

The issue is similar in effect to the HTTP/2 Rapid Reset attack but has a different on-the-wire signature.
