CVE-2026-33658
Ruby on Rails Active Storage is affected by a DoS vulnerability in the proxy mode where the HTTP Range header can include thousands of small ranges, causing disproportionate CPU usage. This impacts Rails applications using Active Storage prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1. A patch ha...
Protection Mechanism Failure
github.com/envoyproxy/envoy is vulnerable to Protection Mechanism Failure. The vulnerability is due to accepting and forwarding client data before a successful 2xx response in TCP proxy mode, which allows an attacker to cause desynchronization when upstream proxies reject the CONNECT request...
Rails Active Storage has a possible DoS vulnerability in proxy mode via multi-range requests
Impact Active Storage's proxy controller does not limit the number of byte ranges in an HTTP Range header. A request with thousands of small ranges causes disproportionate CPU usage compared to a normal request for the same file, possibly resulting in a DoS vulnerability. Releases The fixed...

CVE-2026-33174 Rails Active Storage has a possible DoS vulnerability when in proxy mode via Range requests
Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when serving files through Active Storage's proxy delivery mode, the proxy controller loads the entire requested byte range into memory before sending it. A request...

CVE-2026-33174
Active Storage in Rails is vulnerable when using the proxy delivery mode. A request with a large or unbounded Range header (for example, bytes=0-) can cause the proxy controller to load the entire requested byte range into memory, potentially exhausting memory and enabling DoS. Affected versions ...

CVE-2026-32302 OpenClaw: Untrusted web origins can obtain authenticated operator.admin access in trusted-proxy mode
OpenClaw is a personal AI assistant. Prior to 2026.3.11, browser-originated WebSocket connections could bypass origin validation when gateway.auth.mode was set to trusted-proxy and the request arrived with proxy headers. A page served from an untrusted origin could connect through a trusted rever...

CVE-2025-64763
A flaw was found in Envoy. This vulnerability allows a de-synchronized CONNECT tunnel state via accepting client data before issuing a 2xx response and forwarding it to the upstream TCP Transmission Control Protocol connection when configured in TCP Transmission Control Protocol proxy mode to...
BIT-ENVOY-2025-64763 Envoy forwards early CONNECT data in TCP proxy mode
Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier, when Envoy is configured in TCP proxy mode to handle CONNECT requests, it accepts client data before issuing a 2xx response and forwards that data to the upstream TCP connection. If a forwardi...
