CVE-2026-49754 HTTP/2 CONTINUATION flood in Mint client via unbounded header-block accumulation

Allocation of Resources Without Limits or Throttling vulnerability in elixir-mint Mint allows attacker-controlled HTTP/2 servers to exhaust memory in a Mint client HTTP/2 CONTINUATION flood. When Mint's HTTP/2 receive path observes a HEADERS frame without the ENDHEADERS flag, the unparsed...

CVE-2026-31935

Suricata is a network IDS, IPS and NSM engine. Prior to versions 7.0.15 and 8.0.4, flooding of craft HTTP2 continuation frames can lead to memory exhaustion, usually resulting in the Suricata process being shut down by the operating system. This issue has been patched in versions 7.0.15 and 8.0.4...

Important: ecs-service-connect-agent

Issue Overview: Envoy is a cloud-native, open source edge and service proxy. The HTTP/2 protocol stack in Envoy versions prior to 1.29.3, 1.28.2, 1.27.4, and 1.26.8 are vulnerable to CPU exhaustion due to flood of CONTINUATION frames. Envoy's HTTP/2 codec allows the client to send an unlimited...

AZL-39550 CVE-2023-45288 affecting package multus for versions less than 4.0.2-3

An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no...

AZL-34892 CVE-2023-39325 affecting package kube-vip-cloud-provider for versions less than 0.0.10-1

A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a ne...

HTTP/2: flood using SETTINGS frames results in unbounded memory growth

A flaw was found in HTTP/2. Using SETTINGS frames and queuing of SETTINGS ACK frames, a flood could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

HTTP/2: flood using PING frames results in unbounded memory growth

A flaw was found in HTTP/2. Using PING frames and queuing of response PING ACK frames, a flood attack could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...
