CVE Severity Published▾ Status Exploitation Description
CVE-2026-28369 Critical 2026-03-27 No exploit published No public exploit 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-2026-28368 Critical 2026-03-27 No exploit published No public exploit 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-2026-28367 Critical 2026-03-27 No exploit published No public exploit 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-2025-12543 Critical 2026-01-07 No exploit published Proof of concept only A flaw was found in the Undertow HTTP server core, which is used in WildFly, JBoss EAP, and other Java applications. The Undertow library fails to properly validate the Host header in incoming HTTP requests.As a result, requests containing malformed or malicious Host headers are processed without rejection, enabling attackers to poison caches, perform internal network scans, or hijack user sessions.
CVE-2021-31917 Critical 2021-09-21 Not applicable No public exploit A flaw was found in Red Hat DataGrid 8.x (8.0.0, 8.0.1, 8.1.0 and 8.1.1) and Infinispan (10.0.0 through 12.0.0). An attacker could bypass authentication on all REST endpoints when DIGEST is used as the authentication method. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2019-14887 Critical 2020-03-16 Outside Waratek scope No public exploit A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption. This could lead to a leak of the data being passed over the network. Wildfly version 7.2.0.GA, 7.2.3.GA and 7.2.5.CR2 are believed to be vulnerable.
CVE-2019-14892 Critical 2020-03-02 No exploit published No public exploit A flaw was discovered in jackson-databind in versions before 2.9.10, 2.8.11.5 and 2.6.7.3, where it would permit polymorphic deserialization of a malicious object using commons-configuration 1 and 2 JNDI classes. An attacker could use this flaw to execute arbitrary code.
CVE-2019-10158 Critical 2020-01-02 No exploit published No public exploit A flaw was found in Infinispan through version 9.4.14.Final. An improper implementation of the session fixation protection in the Spring Session integration can result in incorrect session handling.
CVE-2019-10212 Critical 2019-10-02 Outside Waratek scope No public exploit A flaw was found in, all under 2.0.20, in the Undertow DEBUG log for io.undertow.request.security. If enabled, an attacker could abuse this flaw to obtain the user's credentials from the log files.
CVE-2019-3888 Critical 2019-06-12 Outside Waratek scope No public exploit A vulnerability was found in Undertow web server before 2.0.21. An information exposure of plain text credentials through log files because Connectors.executeRootHandler:402 logs the HttpServerExchange object at ERROR level using UndertowLogger.REQUEST_LOGGER.undertowRequestFailed(t, exchange)
CVE-2015-7501 Critical 2017-11-09 Protected by Waratek Exploited Red Hat JBoss A-MQ 6.x; BPM Suite (BPMS) 6.x; BRMS 6.x and 5.x; Data Grid (JDG) 6.x; Data Virtualization (JDV) 6.x and 5.x; Enterprise Application Platform 6.x, 5.x, and 4.3.x; Fuse 6.x; Fuse Service Works (FSW) 6.x; Operations Network (JBoss ON) 3.x; Portal 6.x; SOA Platform (SOA-P) 5.x; Web Server (JWS) 3.x; Red Hat OpenShift/xPAAS 3.x; and Red Hat Subscription Asset Manager 1.3 allow remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the Apache Commons Collections (ACC) library.
