VCID-p645-xsq3-pfc2
Aliases: CVE-2026-28369 GHSA-vqqj-9cmv-hx43 |
Undertow is Vulnerable to HTTP Request/Response Smuggling 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. |
Affected by 0 other vulnerabilities. |

Undertow is Vulnerable to HTTP Request/Response Smuggling 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. |

Aliases: CVE-2026-28367 GHSA-3gv6-g396-9v4r |
Undertow is Vulnerable to HTTP Request/Response Smuggling 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. |
