CVE-2024-4540 1 Redhat 3 Build Keycloak, Red Hat Single Sign On, Rhosemc 2026-10-09 7.5 High
A flaw was found in Keycloak in OAuth 2.0 Pushed Authorization Requests (PAR). Client-provided parameters were found to be included in plain text in the KC_RESTART cookie returned by the authorization server's HTTP response to a `request_uri` authorization request, possibly leading to an information disclosure vulnerability.
CVE-2024-3656 1 Redhat 3 Build Keycloak, Jboss Enterprise Application Platform, Red Hat Single Sign On 2026-10-09 8.1 High
A flaw was found in Keycloak. Certain endpoints in Keycloak's admin REST API allow low-privilege users to access administrative functionalities. This flaw allows users to perform actions reserved for administrators, potentially leading to data breaches or system compromise.
CVE-2026-105301 1 Redhat 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more 2026-10-09 4 Medium
A flaw was found in the X.509 client-certificate authenticator of Keycloak, a solution for identity and access management. The issue occurs when the server is configured to check certificate revocation using CRL Distribution Points or OCSP. An attacker can provide a specially crafted certificate that points to a malicious server, causing Keycloak to make unauthorized outbound requests to internal or external endpoints before the certificate is fully validated. This can lead to a blind server-side request forgery (SSRF) attack.
CVE-2026-105305 1 Redhat 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more 2026-10-09 5.4 Medium
A flaw was found in the OIDC implementation of Keycloak, specifically within the Device Authorization Grant flow. This component allows devices with limited input capabilities to obtain security tokens. The issue occurs because the flow fails to check the minimum authentication level required by a client configuration. This allows an attacker who has stolen a user's password to bypass mandatory multi-factor authentication and gain unauthorized access to the Keycloak Admin REST API.
CVE-2026-107623 1 Redhat 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more 2026-10-09 4.3 Medium
A flaw was found in the OIDC Dynamic Client Registration (DCR) component of Keycloak. A bug in the response serialization causes the backchannel logout offline token revocation setting to be omitted from responses. When a client performs a standard update, this missing information causes the setting to be silently disabled. As a result, offline tokens may remain valid even after a user session is terminated via backchannel logout.
CVE-2026-107121 1 Redhat 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more 2026-10-09 6.5 Medium
A flaw was found in the SMTP email configuration handling of the keycloak-services component. When the STARTTLS option is enabled, Keycloak fails to strictly enforce an encrypted connection, allowing it to fall back to unencrypted communication if the encryption request is tampered with. An attacker who can intercept network traffic can exploit this to capture sensitive email credentials and message content in plain text.
CVE-2026-107604 1 Redhat 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more 2026-10-09 4.9 Medium
A flaw was found in the installation provider and client registration endpoints of the Keycloak identity management service. A realm administrator with only the read-only view-clients role can access the active primary secret of any confidential client, which should normally be restricted. This exposed secret can be used to impersonate the client and gain unauthorized access to its associated service account permissions.
CVE-2026-107889 1 Redhat 2 Build Keycloak, Red Hat Single Sign On 2026-10-09 5.5 Medium
A flaw was found in the login theme rendering component of Keycloak. The issue occurs because the security filter responsible for cleaning user input can be bypassed, allowing a realm administrator to store malicious scripts in display fields. This could result in unauthorized JavaScript execution in the browsers of users visiting the login page, potentially leading to data exposure or session interference.
CVE-2026-19611 1 Redhat 15 Apache Camel Quarkus, Build Keycloak, Build Of Apache Camel For Quarkus and 12 more 2026-10-08 7.4 High
A flaw was found in WildFly Elytron. Password hashing and verification normalize input with Unicode NFKC, which can collapse fullwidth characters to ASCII equivalents. A remote attacker can more easily guess affected passwords by using an ASCII-only dictionary against accounts whose passwords were intended to include those non-ASCII characters, leading to unauthorized access.
CVE-2021-40690 4 Apache, Debian, Oracle and 1 more 27 Cxf, Santuario Xml Security For Java, Tomee and 24 more 2026-10-08 7.5 High
All versions of Apache Santuario - XML Security for Java prior to 2.2.3 and 2.1.7 are vulnerable to an issue where the "secureValidation" property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.
CVE-2021-21290 6 Debian, Netapp, Netty and 3 more 27 Debian Linux, Active Iq Unified Manager, Cloud Secure Agent and 24 more 2026-10-08 6.2 Medium
Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty before version 4.1.59.Final there is a vulnerability on Unix-like systems involving an insecure temp file. When netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. On unix-like systems, the temporary directory is shared between all user. As such, writing to this directory using APIs that do not explicitly set the file/directory permissions can lead to information disclosure. Of note, this does not impact modern MacOS Operating Systems. The method "File.createTempFile" on unix-like systems creates a random file, but, by default will create this file with the permissions "-rw-r--r--". Thus, if sensitive information is written to this file, other local users can read this information. This is the case in netty's "AbstractDiskHttpData" is vulnerable. This has been fixed in version 4.1.59.Final. As a workaround, one may specify your own "java.io.tmpdir" when you start the JVM or use "DefaultHttpDataFactory.setBaseDir(...)" to set the directory to something that is only readable by the current user.
CVE-2021-44906 2 Redhat, Substack 12 Enterprise Linux, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Eus and 9 more 2026-10-08 9.8 Critical
Minimist <=1.2.5 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
CVE-2021-37714 5 Jsoup, Netapp, Oracle and 2 more 25 Jsoup, Management Services For Element Software And Netapp Hci, Banking Trade Finance and 22 more 2026-10-08 7.5 High
jsoup is a Java library for working with HTML. Those using jsoup versions prior to 1.14.2 to parse untrusted HTML or XML may be vulnerable to DOS attacks. If the parser is run on user supplied input, an attacker may supply content that causes the parser to get stuck (loop indefinitely until cancelled), to complete more slowly than usual, or to throw an unexpected exception. This effect may support a denial of service attack. The issue is patched in version 1.14.2. There are a few available workarounds. Users may rate limit input parsing, limit the size of inputs based on system resources, and/or implement thread watchdogs to cap and timeout parse runtimes.
CVE-2020-11620 5 Debian, Fasterxml, Netapp and 2 more 26 Debian Linux, Jackson-databind, Active Iq Unified Manager and 23 more 2026-10-08 8.1 High
FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to org.apache.commons.jelly.impl.Embedded (aka commons-jelly).
CVE-2019-14379 7 Apple, Debian, Fasterxml and 4 more 37 Xcode, Debian Linux, Jackson-databind and 34 more 2026-10-08 9.8 Critical
SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution.
CVE-2019-12086 3 Debian, Fasterxml, Redhat 12 Debian Linux, Jackson-databind, Amq Streams and 9 more 2026-10-08 7.5 High
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9. When Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an attacker can host a crafted MySQL server reachable by the victim, an attacker can send a crafted JSON message that allows them to read arbitrary local files on the server. This occurs because of missing com.mysql.cj.jdbc.admin.MiniAdmin validation.
CVE-2020-25649 7 Apache, Fasterxml, Fedoraproject and 4 more 50 Iotdb, Jackson-databind, Fedora and 47 more 2026-10-08 7.5 High
A flaw was found in FasterXML Jackson Databind, where it did not have entity expansion secured properly. This flaw allows vulnerability to XML external entity (XXE) attacks. The highest threat from this vulnerability is data integrity.
CVE-2020-11619 5 Debian, Fasterxml, Netapp and 2 more 31 Debian Linux, Jackson-databind, Active Iq Unified Manager and 28 more 2026-10-08 8.1 High
FasterXML jackson-databind 2.x before 2.9.10.4 mishandles the interaction between serialization gadgets and typing, related to org.springframework.aop.config.MethodLocatingFactoryBean (aka spring-aop).
CVE-2020-13956 5 Apache, Netapp, Oracle and 2 more 27 Httpclient, Active Iq Unified Manager, Snapcenter and 24 more 2026-10-08 5.3 Medium
Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.
CVE-2024-7885 1 Redhat 21 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 18 more 2026-10-08 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.
