CVE:CVE-2026-3260 vulnerable 2026-06-08 08:01:18.284232 Details available

CVE:CVE-2026-28369 vulnerable 2026-06-08 07:55:15.208763 Undertow: undertow: request smuggling via malformed http request headers
HIGH (8.7)
A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure.

CVE:CVE-2026-28368 vulnerable 2026-06-08 07:55:15.203942 Undertow: undertow: request smuggling via inconsistent header parsing
HIGH (8.7)
A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing unauthorized resources.

CVE:CVE-2026-28367 vulnerable 2026-06-08 07:55:15.202662 Undertow: undertow: request smuggling via `\r\r\r` as a header block terminator
HIGH (8.7)
A flaw was found in Undertow. A remote attacker can exploit this vulnerability by sending `\r\r\r` as a header block terminator. This can be used for request smuggling with certain proxy servers, such as older versions of Apache Traffic Server and Google Cloud Classic Application Load Balancer, potentially leading to unauthorized access or manipulation of web requests.

CVE:CVE-2025-9784 vulnerable 2026-06-08 07:47:09.799238 Undertow: undertow madeyoureset http/2 ddos vulnerability
HIGH (7.5)
A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS).
