CVE-2026-82440	High	2026-11-09	Protected by Waratek	No public exploit	Description Nimbus instantiates the class named by a topology's `topology.scheduler.strategy` when scheduling it. The allowlist intended to constrain that choice, `nimbus.scheduler.strategy.class.whitelist`, was treated as "allow any class" when unset, and it had no entry in the shipped `defaults.yaml`, so unset was the shipped state. An authenticated submitter could therefore cause Nimbus to instantiate any class on the Nimbus classpath that has a no-argument constructor. Storm's own production artifacts contain classes with side effects suitable for this: instantiating `org.apache.storm.testing.InProcessZookeeper` starts a ZooKeeper server with its own threads and sockets and nothing closes it, and `org.apache.storm.LocalCluster` behaves similarly. Repeated submissions therefore consume threads, sockets and memory in the most privileged daemon in the cluster. Mitigation Upgrade to 3.1.0, where an unset allowlist means the strategies shipped with Storm rather than any class. Note that this is a behaviour change: a cluster running an out-of-tree scheduler strategy without an explicit allowlist will have those topologies refused until the class is added to `nimbus.scheduler.strategy.class.whitelist`. The rejection message names the refused class and the configuration key. Users who cannot upgrade immediately should set `nimbus.scheduler.strategy.class.whitelist` explicitly to the strategies they intend to permit.
CVE-2026-78636	Medium	2026-11-08	Protected by Waratek	No public exploit	IBM WebSphere Application Server Liberty 17.0.0.3 through 26.0.0.10 is affected by an information disclosure vulnerability due to unsafe class reflection in the JMX REST connector body parser.
CVE-2026-73098	Critical	2026-11-05	Protected by Waratek	No public exploit	Improper control of dynamically-loaded code vulnerability in Apache Juneau. When Apache Juneau parses a value into a property of type java.lang.Class (including parameterized forms), the default class swap loaded the named class with initialization enabled, so input naming a class on the application classpath ran that class's static initializer. The impact depends on the classes present in the deployment. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue.
CVE-2026-71253	Critical	2026-10-19	Protected by Waratek	No public exploit	Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache Johnzon. ClassConverter loads & static-initializes an attacker-named class from untrusted JSON. This issue affects Apache Johnzon: from 1.0.0 before 2.2.0. Users are recommended to upgrade to version 1.3.1 (javax namespace) or 2.2.0 (jakarta specification namespace), which fixes the issue.
CVE-2026-92415	Medium	2026-10-07	Protected by Waratek	No public exploit	— Use of Externally-Controlled Input to Select Classes or Code vulnerability in Apache Jackrabbit's WebDAV/Davex client. A malicious WebDAV/DavEx server, or an attacker able to intercept the connection, can cause the client to instantiate arbitrary classes from its classpath, which can lead to arbitrary file creation or truncation. Only applications that use jackrabbit-spi2dav (directly or through jackrabbit-jcr2dav) to connect to a remote repository are affected. Jackrabbit servers are not affected. Category: unsafe reflection on wire data (HIGH). This issue affects Apache Jackrabbit: from 2.23.0 through 2.23.5, from 2.22.0 through 2.22.4, from 2.20.0 through 2.20.17. Users are recommended to upgrade to versions 2.23.6, 2.22.5, or 2.20.18 which fix the issue.
CVE-2026-70410	High	2026-09-22	Protected by Waratek	No public exploit	Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache Calcite Avatica. Plugin instantiation (via AvaticaUtils#instantiatePlugin and other methods) initializes arbitrary classes via unrestricted calls to Class.forName(String) which by default triggers initialization. This may lead to the execution of static initializer blocks in arbitrary classes present in the classpath. The instantiation APIs should initialize and instantiate only classes implementing the specified plugin interface passed as input in conjunction with the desired classname. At the moment of writing, there are no well-known or widely used classes with dangerous static initializer blocks so the severity is low. This issue affects Apache Calcite Avatica: before 1.29.0. Users are recommended to upgrade to version 1.29.0, which fixes the issue.
CVE-2026-92126	High	2026-09-16	Protected by Waratek	No public exploit	Jenkins Script Security Plugin 1415.v9a_f9b_3a_c253d and earlier does not reject @Builder annotations whose builderStrategy member names an arbitrary class, allowing attackers with permission to define and run sandboxed scripts, including Pipelines, to execute code outside the sandbox if a suitable class is present on the classpath of the component that evaluates the script.
CVE-2026-47875	Critical	2026-08-27	Protected by Waratek	No public exploit	Applications that deserialize execution contexts with Jackson2ExecutionContextStringSerializer are vulnerable to a deserialization attack if they use an untrusted data source for the job repository. The JobParameterDeserializer does not properly enforce the trusted-types allowlist, allowing an attacker to craft malicious input that can lead to arbitrary code execution, including known Jackson RCE gadgets. Spring Batch 6.0.0 - 6.0.4 Spring Batch 5.2.0 - 5.2.6
CVE-2026-19135	Medium	2026-08-13	Protected by Waratek	No public exploit	A JEXL expression sandbox bypass exists in multiple versions of OpenNMS Meridian and Horizon. A low-privileged authenticated user can submit a crafted expression to the Measurements REST API that escapes the sandbox and loads arbitrary Java classes on the server. This can potentially allow an attacker to gain access to confidential information and compromise integrity. The solution is to upgrade to Meridian 2024.3.12, 2025.0.9 and Horizon 36.0.3 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet.
CVE-2026-8400	Critical	2026-08-05	Protected by Waratek	No public exploit	IBM WebSphere Application Server 8.5, and 9.0 and IBM WebSphere Application Server - Liberty Continuous delivery has a flaw in the ORB component in IBM SDK, Java Technology Edition, may allow a malicious IIOP server to induce loading and instantation of arbitrary classes.
CVE-2026-63317	Medium	2026-07-24	Protected by Waratek	No public exploit	Arbitrary Class Instantiation via XML Feature Generator Descriptor and Format Name in Apache OpenNLP Versions Affected: - before 2.5.10 - before 3.0.0-M5 Description: Three code paths in Apache OpenNLP load a class by its fully-qualified name via Class.forName() and invoke its no-arg constructor without any prior validation of the class name or its type. The affected paths are: (1) GeneratorFactory, which reads the class attribute of generator elements in an XML feature generator descriptor; such descriptors are embedded as artifacts in model archives (e.g. TokenNameFinder and POSTagger models) and are parsed during model loading, so an attacker who can supply a crafted model archive controls the class name directly. (2) StreamFactoryRegistry.getFactory(Class, String), which falls back to interpreting an unregistered format name as the fully-qualified class name of an ObjectStreamFactory; this is exploitable in applications that pass untrusted format names (e.g. exposing the -format parameter of the command-line tooling to external input). (3) StringInterners, which instantiates the interner implementation named by the opennlp.interner.class system property; this value is normally deployer-controlled, so it is hardened as defense in depth rather than being independently attacker-reachable. Exploitation requires a class with attacker-useful side effects in its static initializer or no-arg constructor (JNDI lookup, outbound network I/O, filesystem access) to be present on the classpath, so this is not drop-in remote code execution. T Mitigation: Upgrade to a fixed release. The fix routes all three paths through ExtensionLoader.instantiateExtension(...), which consults a package-prefix allowlist before Class.forName() is invoked, so a disallowed class is never loaded, initialized, or constructed. Classes under the opennlp. prefix remain permitted by default. Deployments that load models referencing feature generator factories, object stream factories, or string interners outside opennlp.* must opt those packages in, either programmatically via ExtensionLoader.registerAllowedPackage(String) before the first model load, or by setting the OPENNLP_EXT_ALLOWED_PACKAGES system property to a comma-separated list of allowed package prefixes. Users who cannot upgrade immediately should ensure all model files and format names are sourced from trusted origins and should audit their classpath for classes with side-effecting static initializers or constructors.
CVE-2026-40008	Critical	2026-07-10	Protected by Waratek	No public exploit	Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache IoTDB. The pipe processor reads a fully qualified Java class name and instantiates it using Class.forName().newInstance() without any validation or allowlisting. This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.
CVE-2026-46718	Medium	2026-06-02	Protected by Waratek	No public exploit	Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache Calcite. This issue affects Apache Calcite: from 1.5.0 before 1.42. Users are recommended to upgrade to version 1.42, which fixes the issue.
CVE-2026-8178	Critical	2026-05-08	Protected by Waratek	No public exploit	An issue exists in Amazon Redshift JDBC Driver versions prior to 2.2.2. Under certain conditions, the driver could load and execute arbitrary classes when processing JDBC connection URL parameters. An actor who can influence the connection URL could potentially execute code in the application context, provided a suitable class is available on the application's classpath. To mitigate this issue, users should upgrade to version 2.2.2 or later.
CVE-2021-31522	Critical	2022-01-06	Protected by Waratek	No public exploit	Kylin can receive user input and load any class through Class.forName(...). This issue affects Apache Kylin 2 version 2.6.6 and prior versions; Apache Kylin 3 version 3.1.2 and prior versions; Apache Kylin 4 version 4.0.0 and prior versions.
CVE-2019-19899	Critical	2019-12-19	Protected by Waratek	No public exploit	Pebble Templates 3.1.2 allows attackers to bypass a protection mechanism (intended to block access to instances of java.lang.Class) because getClass is accessible via the public static java.lang.Class java.lang.Class.forName(java.lang.Module,java.lang.String) signature.
CVE-2019-10174	High	2019-11-25	Protected by Waratek	No public exploit	A vulnerability was found in Infinispan such that the invokeAccessibly method from the public class ReflectionUtil allows any application class to invoke private methods in any class with Infinispan's privileges. The attacker can use reflection to introduce new, malicious behavior into the application.
CVE-2019-3834	High	2019-10-03	Protected by Waratek	No public exploit	It was found that the fix for CVE-2014-0114 had been reverted in JBoss Operations Network 3 (JON). This flaw allows attackers to manipulate ClassLoader properties on a vulnerable server. Exploits that have been published rely on ClassLoader properties that are exposed such as those in JON 3. Additional information can be found in the Red Hat Knowledgebase article: https://access.redhat.com/site/solutions/869353. Note that while multiple products released patches for the original CVE-2014-0114 flaw, the reversion described by this CVE-2019-3834 flaw only occurred in JON 3.
CVE-2019-1003041	Critical	2019-03-28	Protected by Waratek	No public exploit	A sandbox bypass vulnerability in Jenkins Pipeline: Groovy Plugin 2.64 and earlier allows attackers to invoke arbitrary constructors in sandboxed scripts.
CVE-2019-1003040	Critical	2019-03-28	Protected by Waratek	No public exploit	A sandbox bypass vulnerability in Jenkins Script Security Plugin 1.55 and earlier allows attackers to invoke arbitrary constructors in sandboxed scripts.
CVE-2017-7536	High	2018-01-10	Protected by Waratek	No public exploit	In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue().

Description Nimbus instantiates the class named by a topology's `topology.scheduler.strategy` when scheduling it. The allowlist intended to constrain that choice, `nimbus.scheduler.strategy.class.whitelist`, was treated as "allow any class" when unset, and it had no entry in the shipped `defaults.yaml`, so unset was the shipped state. An authenticated submitter could therefore cause Nimbus to instantiate any class on the Nimbus classpath that has a no-argument constructor. Storm's own production artifacts contain classes with side effects suitable for this: instantiating `org.apache.storm.testing.InProcessZookeeper` starts a ZooKeeper server with its own threads and sockets and nothing closes it, and `org.apache.storm.LocalCluster` behaves similarly. Repeated submissions therefore consume threads, sockets and memory in the most privileged daemon in the cluster. Mitigation Upgrade to 3.1.0, where an unset allowlist means the strategies shipped with Storm rather than any class. Note that this is a behaviour change: a cluster running an out-of-tree scheduler strategy without an explicit allowlist will have those topologies refused until the class is added to `nimbus.scheduler.strategy.class.whitelist`. The rejection message names the refused class and the configuration key. Users who cannot upgrade immediately should set `nimbus.scheduler.strategy.class.whitelist` explicitly to the strategies they intend to permit.
