CVE-2026-3121 1 Redhat 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more 2026-04-02 N/A 6.5 MEDIUM
A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.
CVE-2026-4366 1 Redhat 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more 2026-04-01 N/A 5.8 MEDIUM
A flaw was identified in Keycloak, an identity and access management solution, where it improperly follows HTTP redirects when processing certain client configuration requests. This behavior allows an attacker to trick the server into making unintended requests to internal or restricted resources. As a result, sensitive internal services such as cloud metadata endpoints could be accessed. This issue may lead to information disclosure and enable attackers to map internal network infrastructure.
CVE-2026-4874 1 Redhat 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more 2026-04-01 N/A 3.1 LOW
A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the `client_session_host` parameter during refresh token requests. This occurs when a Keycloak client is configured to use the `backchannel.logout.url` with the `application.session.host` placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.
CVE-2026-28368 1 Redhat 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more 2026-03-31 N/A 8.7 HIGH
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-2026-28369 1 Redhat 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more 2026-03-31 N/A 8.7 HIGH
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-2024-7341 1 Redhat 4 Build Of Keycloak, Enterprise Linux, Keycloak and 1 more 2026-03-27 N/A 7.1 HIGH
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2026-3009 1 Redhat 4 Build Of Keycloak, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Expansion Pack and 1 more 2026-03-24 N/A 8.1 HIGH
A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.
CVE-2025-9784 1 Redhat 8 Build Of Apache Camel For Spring Boot, Enterprise Linux, Fuse and 5 more 2026-03-18 N/A 7.5 HIGH
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).
CVE-2025-12543 1 Redhat 8 Build Of Apache Camel, Data Grid, Fuse and 5 more 2026-03-18 N/A 9.6 CRITICAL
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-2024-7885 1 Redhat 9 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Build Of Keycloak and 6 more 2026-01-19 N/A 7.5 HIGH
A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
CVE-2023-44487 32 Akka, Amazon, Apache and 29 more 313 Http Server, Opensearch Data Prepper, Apisix and 310 more 2025-11-07 N/A 7.5 HIGH
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2023-48795 42 9bis, Apache, Apple and 39 more 68 Kitty, Sshd, Sshj and 65 more 2025-11-04 N/A 5.9 MEDIUM
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust.
CVE-2023-5379 1 Redhat 3 Jboss Enterprise Application Platform, Single Sign-on, Undertow 2025-10-25 N/A 7.5 HIGH
A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS).
CVE-2019-10219 3 Netapp, Oracle, Redhat 195 Active Iq Unified Manager, Element, Management Services For Element Software And Netapp Hci and 192 more 2025-07-07 4.3 MEDIUM 6.1 MEDIUM
A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.
CVE-2024-1132 1 Redhat 10 Build Of Keycloak, Jboss Middleware Text-only Advisories, Keycloak and 7 more 2025-06-30 N/A 8.1 HIGH
A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL.
CVE-2024-1635 2 Netapp, Redhat 9 Active Iq Unified Manager, Oncommand Workflow Automation, Fuse and 6 more 2025-06-25 N/A 7.5 HIGH
A vulnerability was found in Undertow. This vulnerability impacts a server that supports the wildfly-http-client protocol. Whenever a malicious user opens and closes a connection with the HTTP port of the server and then closes the connection immediately, the server will end with both memory and open file limits exhausted at some point, depending on the amount of memory available. At HTTP upgrade to remoting, the WriteTimeoutStreamSinkConduit leaks connections if RemotingConnection is closed by Remoting ServerConnectionOpenListener. Because the remoting connection originates in Undertow as part of the HTTP upgrade, there is an external layer to the remoting connection. This connection is unaware of the outermost layer when closing the connection during the connection opening procedure. Hence, the Undertow WriteTimeoutStreamSinkConduit is not notified of the closed connection in this scenario. Because WriteTimeoutStreamSinkConduit creates a timeout task, the whole dependency tree leaks via that task, which is added to XNIO WorkerThread. So, the workerThread points to the Undertow conduit, which contains the connections and causes the leak.
CVE-2023-1932 2 Hibernate, Redhat 5 Hibernate-validator, Codeready Studio, Jboss Enterprise Application Platform and 2 more 2025-06-24 N/A 6.1 MEDIUM
A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.
CVE-2023-0091 1 Redhat 2 Keycloak, Single Sign-on 2025-04-09 N/A 3.8 LOW
A flaw was found in Keycloak, where it did not properly check client tokens for possible revocation in its client credential flow. This flaw allows an attacker to access or modify potentially sensitive information.
CVE-2023-0105 1 Redhat 2 Keycloak, Single Sign-on 2025-04-09 N/A 6.5 MEDIUM
A flaw was found in Keycloak. This flaw allows impersonation and lockout due to the email trust not being handled correctly in Keycloak. An attacker can shadow other users with the same email and lockout or impersonate them.
CVE-2022-4492 1 Redhat 10 Build Of Quarkus, Integration Camel For Spring Boot, Integration Camel K and 7 more 2025-03-12 N/A 7.5 HIGH
The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
