| CVE-2024-1722 | 1 Redhat | 3 Build Keycloak, Keycloak, Red Hat Single Sign On | 2025-08-07 | 3.7 Low |
| A flaw was found in Keycloak. In certain conditions, this issue may allow a remote unauthenticated attacker to block other accounts from logging in. | ||||
| CVE-2023-6927 | 1 Redhat | 5 Build Keycloak, Keycloak, Red Hat Single Sign On and 2 more | 2025-08-07 | 4.6 Medium |
| A flaw was found in Keycloak. This issue may allow an attacker to steal authorization codes or tokens from clients using a wildcard in the JARM response mode "form_post.jwt" which could be used to bypass the security patch implemented to address CVE-2023-6134. | ||||
| CVE-2023-6787 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Keycloak and 1 more | 2025-08-07 | 6.5 Medium |
| A flaw was found in Keycloak that occurs from an error in the re-authentication mechanism within org.keycloak.authentication. This flaw allows hijacking an active Keycloak session by triggering a new authentication process with the query parameter "prompt=login," prompting the user to re-enter their credentials. If the user cancels this re-authentication by selecting "Restart login," an account takeover may occur, as the new session, with a different SUB, will possess the same SID as the previous session. | ||||
| CVE-2023-6544 | 1 Redhat | 3 Build Keycloak, Red Hat Single Sign On, Rhosemc | 2025-08-07 | 5.4 Medium |
| A flaw was found in the Keycloak package. This issue occurs due to a permissive regular expression hardcoded for filtering which allows hosts to register a dynamic client. A malicious user with enough information about the environment could jeopardize an environment with this specific Dynamic Client Registration and TrustedDomain configuration previously unauthorized. | ||||
| CVE-2023-6134 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2025-08-07 | 4.6 Medium |
| A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748. | ||||
| CVE-2023-6563 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2025-08-07 | 7.7 High |
| An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system. | ||||
| CVE-2024-3653 | 1 Redhat | 17 Amq Streams, Apache Camel Hawtio, Build Keycloak and 14 more | 2025-08-06 | 5.3 Medium |
| A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured. The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack. The attacker needs to be able to reach the server with a normal HTTP request. | ||||
| CVE-2023-5379 | 1 Redhat | 11 Jboss Data Grid, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Eus and 8 more | 2025-08-04 | 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-2020-11023 | 8 Debian, Drupal, Fedoraproject and 5 more | 78 Debian Linux, Drupal, Fedora and 75 more | 2025-07-30 | 6.9 Medium |
| In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0. | ||||
| CVE-2021-39144 | 6 Debian, Fedoraproject, Netapp and 3 more | 22 Debian Linux, Fedora, Snapmanager and 19 more | 2025-07-30 | 8.5 High |
| XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose. | ||||
| CVE-2023-44487 | 32 Akka, Amazon, Apache and 29 more | 367 Http Server, Opensearch Data Prepper, Apisix and 364 more | 2025-07-30 | 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-2024-11831 | 1 Redhat | 33 Acm, Advanced Cluster Security, Ansible Automation Platform and 30 more | 2025-07-23 | 5.4 Medium |
| A flaw was found in npm-serialize-javascript. The vulnerability occurs because the serialize-javascript module does not properly sanitize certain inputs, such as regex or other JavaScript object types, allowing an attacker to inject malicious code. This code could be executed when deserialized by a web browser, causing Cross-site scripting (XSS) attacks. This issue is critical in environments where serialized data is sent to web clients, potentially compromising the security of the website or web application using this package. | ||||
| CVE-2024-10234 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Jboss Data Grid and 5 more | 2025-07-23 | 6.1 Medium |
| A vulnerability was found in Wildfly, where a user may perform Cross-site scripting in the Wildfly deployment system. This flaw allows an attacker or insider to execute a deployment with a malicious payload, which could trigger undesired behavior against the server. | ||||
| CVE-2025-23367 | 1 Redhat | 7 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 4 more | 2025-07-22 | 6.5 Medium |
| A flaw was found in the Wildfly Server Role Based Access Control (RBAC) provider. When authorization to control management operations is secured using the Role Based Access Control provider, a user without the required privileges can suspend or resume the server. A user with a Monitor or Auditor role is supposed to have only read access permissions and should not be able to suspend the server. The vulnerability is caused by the Suspend and Resume handlers not performing authorization checks to validate whether the current user has the required permissions to proceed with the action. | ||||
| CVE-2024-8698 | 1 Redhat | 4 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On and 1 more | 2025-07-10 | 7.7 High |
| A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks. | ||||
| CVE-2022-23302 | 6 Apache, Broadcom, Netapp and 3 more | 44 Log4j, Brocade Sannav, Snapmanager and 41 more | 2025-07-07 | 8.8 High |
| JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||
| CVE-2020-35509 | 1 Redhat | 2 Keycloak, Red Hat Single Sign On | 2025-06-30 | 5.4 Medium |
| A flaw was found in keycloak affecting versions 11.0.3 and 12.0.0. An expired certificate would be accepted by the direct-grant authenticator because of missing time stamp validations. The highest threat from this vulnerability is to data confidentiality and integrity. | ||||
| CVE-2023-1932 | 2 Hibernate, Redhat | 24 Hibernate-validator, A Mq Clients, Amq Broker and 21 more | 2025-06-24 | 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-2022-1471 | 2 Redhat, Snakeyaml Project | 14 Amq Clients, Amq Streams, Enterprise Linux and 11 more | 2025-06-18 | 8.3 High |
| SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization. Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization. We recommend upgrading to version 2.0 and beyond. | ||||
| CVE-2025-2559 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2025-06-04 | 4.9 Medium |
| A flaw was found in Keycloak. When the configuration uses JWT tokens for authentication, the tokens are cached until expiration. If a client uses JWT tokens with an excessively long expiration time, for example, 24 or 48 hours, the cache can grow indefinitely, leading to an OutOfMemoryError. This issue could result in a denial of service condition, preventing legitimate users from accessing the system. | ||||
