artemis-server: Apache Artemis — session hijack via missing authentication

in Apache Artemis, the REATTACHSESSION handler performs zero authentication — it looks up the session by name only and calls transferConnection unconditionally, migrating the authenticated session to the attacker's connection. The hijacked cluster-bridge session inherits full broker-management...

cxf: org.apache.cxf/cxf-rt-transports-jms: Apache CXF: Arbitrary code execution via untrusted JMS configuration

A flaw was found in Apache CXF. This vulnerability, stemming from an incomplete fix for a previous issue, allows untrusted users who can configure Java Message Service JMS for Apache CXF to achieve arbitrary code execution. This could lead to a complete compromise of the affected system...

wildfly-elytron-realm-token: parameter injection in EAP's elytron oauth2

A flaw was found in EAP's Elytron. An EAP application whose security domain is backed by an Elytron token-realm with oauth2-introspection would allow parameter substitution due to missing URL encoding...

io.netty/netty-codec-http: Netty: Denial of Service via SPDY SETTINGS frame processing

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service DoS...

jackson-databind: jackson-databind: Arbitrary code execution via PolymorphicTypeValidator bypass

A flaw was found in jackson-databind. This vulnerability allows a remote attacker to bypass the PolymorphicTypeValidator PTV when polymorphic typing is enabled and a type identifier contains generic parameters. By crafting a malicious type ID, an attacker can place a denied class as a generic typ...

netty: io.netty/netty-codec-http: Netty: Denial of Service via memory exhaustion in SPDY-to-HTTP codec

A flaw was found in Netty. A remote attacker can exploit a vulnerability in the SpdyHttpDecoder handler of Netty's SPDY-to-HTTP codec. When processing a client-initiated SYNSTREAM frame, the decoder fails to release allocated memory if the stream is reset or content limits are exceeded. This...

openjdk-orb: unauthed class loading via IIOP in EAP

when EAP runs with -secmgr, the openjdk-orb's JDKBridge honours attacker-supplied CDR codebase URLs during object unmarshalling on :3528, allowing an unauthenticated attacker to load and instantiate arbitrary classes from a remote URL in the server JVM before EJB security interceptors run...

artemis-server: artemis-jms-client: artemis-core-client: undertow-core: wildfly-messaging-activemq-subsystem: artemis messaging handlers in Red Hat EAP permit deserialization by default

EAP's Artemis deserialization configuration permits deserialization by default. ObjectMessage.getObject uses ObjectInputStreamWithClassLoader, which implements allow-list/block-list filtering via its checkSecurity/isTrustedType method. However, by default both allow-list and block-list are empty...

undertow-core: Undertow: Denial of Service via WebSocket permessage-deflate processing

A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer method using exponential doubling,...

jackson-databind: Jackson-databind: Security bypass allows arbitrary code execution

A flaw was found in jackson-databind, a library used for processing data. This vulnerability allows an attacker to bypass security controls designed to validate data types. By sending specially crafted input, an attacker can force the system to process untrusted data, which may lead to the...

undertow-core: OOM via missing limits in chunked trailer in EAP's Undertow

A flaw was found in EAP's undertow http/1.1 chunked-transfer decoder. missing limits on size and count would allow an attacker to use an unauthenticated connection to drive the JVM to an OutOfMemory error, stopping all deployments on the listener, and achieving Denial of Service...

wildfly-messaging-activemq-subsystem: artemis-server: jgroups: artemis cluster password leak via jgroups spoof

Artemis and JGroups lack of access controls in certain situations can allow an attacker to spoof a password request in JGroups and subsequently gain access to the cluster. This allows the attacker manage-level authority for provided messaging and queue operations...

jackson-databind: jackson-databind: Ignored properties can be unexpectedly modified

A flaw was found in jackson-databind. This vulnerability occurs in the data-binding functionality where properties intended to be ignored are incorrectly restored and become writable again. An attacker could potentially exploit this by providing input that modifies data through these supposedly...

artemis-server: Apache Artemis — session hijack via missing authentication

in Apache Artemis, the REATTACHSESSION handler performs zero authentication — it looks up the session by name only and calls transferConnection unconditionally, migrating the authenticated session to the attacker's connection. The hijacked cluster-bridge session inherits full broker-management...

cxf: org.apache.cxf/cxf-rt-transports-jms: Apache CXF: Arbitrary code execution via untrusted JMS configuration

A flaw was found in Apache CXF. This vulnerability, stemming from an incomplete fix for a previous issue, allows untrusted users who can configure Java Message Service JMS for Apache CXF to achieve arbitrary code execution. This could lead to a complete compromise of the affected system...

brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...

com.fasterxml.jackson.core/jackson-databind: Jackson-databind: Privilege escalation via improper handling of @JsonUnwrapped properties

A flaw was found in jackson-databind. The UnwrappedPropertyHandler.processUnwrapped method, responsible for handling @JsonUnwrapped properties, replays buffered JSON without properly checking the active view. This allows an attacker to write data to a property annotated with both @JsonView and...

org.apache.cxf/cxf-rt-transports-jms: Apache CXF: Remote Code Execution via untrusted JMS configuration

A flaw was found in Apache CXF. Untrusted users, if allowed to configure Java Message Service JMS for Apache CXF, can exploit this vulnerability to achieve remote code execution RCE. This issue arises from an incomplete fix for a prior security flaw, indicating an alternative path that could lead...

undertow-core: Undertow: Authentication Bypass via AJP ssl_cert/is_ssl Forgery

the Undertow AJP listener honours forged sslcert and isssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP...

com.fasterxml.jackson.core/jackson-databind: Jackson-databind: Privilege escalation via improper handling of @JsonUnwrapped properties

A flaw was found in jackson-databind. The UnwrappedPropertyHandler.processUnwrapped method, responsible for handling @JsonUnwrapped properties, replays buffered JSON without properly checking the active view. This allows an attacker to write data to a property annotated with both @JsonView and...
