CVE-2026-63687: Insufficient Verification of Data Authenticity

Apache CXF's JwtRequestCodeFilter copies all claims from a signed request JWT into the authorization parameter map without excluding security-sensitive parameters. A client that can produce a validly-signed request JWT e.g., one whose clientsecret is known or compromised can thereby substitute th...

CVE-2026-57817: Improper Input Validation

The OpenID Connect Core 1.0 specification mandates that the RP MUST validate the chash parameter when operating in the Hybrid Flow. If an Apache CXF RP is integrated with a non-compliant or misconfigured Identity Provider IdP that omits the chash, the RP becomes vulnerable to Authorization Code...

CVE-2026-66909: Deserialization of Untrusted Data

Apache CXF's JMS transport deserializes the body of any inbound JMS ObjectMessage using native Java deserialization, with no type restrictions in place. Any attacker able to place a message on the service's JMS destination can submit a malicious serialized object, leading to denial of service or,...

CVE-2026-68079: Authentication Bypass by Capture-replay

In Apache CXF's DefaultEncryptingCodeDataProvider, a captured authorization code can be redeemed an unlimited number of times due to a flaw in the implementation of the removeCodeGrant functionality. This violates the RFC requirement that "The authorization code MUST NOT be used more than once."...

CVE-2026-65583: Insufficient Verification of Data Authenticity

Apache CXF’s OIDC relying-party token validation could accept self-issued ID tokens without enforcing required claim checks issuer/subject/audience/time and subjwk binding, enabling authentication bypass with crafted tokens. However, note that self-issued ID tokens are not accepted by default in...

CVE-2026-65432: Improper Restriction of XML External Entity Reference

Apache CXF reads a top-level WSDL through its hardened StaxUtils path, which disables XML DTDs and external entities. However, any or referenced from that top-level WSDL is handed off to WSDL4J, which does not disable DOCTYPE declarations or external entities. As a result, the protections applied...

CVE-2026-68481: Operation on a Resource after Expiration or Release

In Apache CXF's DefaultEncryptingOAuthDataProvider, revoked access tokens still decrypt successfully, and TokenIntrospectionService reports active:true. The same applies to refresh tokens. This violates the RFC stipulations that 'The authorization server MUST invalidate the token.' and...

CVE-2026-64958: Uncontrolled Resource Consumption

An incomplete fix for CVE-2026-50645 means that it is still possible to perform a denial of service attack on Apache CXF by sending a message with many attachment headers. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue...

CVE-2026-54225: Allocation of Resources Without Limits or Throttling

Apache CXF allows to control the maximum attachment size via the "attachment-max-size". Prior to Apache CXF 4.2.3 and 4.1.8 and 3.6.12, there was no default placed on this size, meaning that a denial of service attack is possible if the user doesn't explicitly set the limit. Users should update t...

CVE-2026-57819: Uncontrolled Resource Consumption

Apache CXF allows to set a limit on the number of form parameters in a JAX-RS message via the "maxFormParameterCount" configuration option. However, no default limit is set which may lead to denial of service attacks when processing requests with very large numbers of form parameters. Users are...

Apache CXF < 4.0.4 - Aegis DataBinding SSRF / Local File Read

Apache CXF before 4.0.4, 3.6.3 and 3.5.8 has a Server-Side Request Forgery SSRF vulnerability when using the Aegis DataBinding. The XOP Include mechanism in multipart SOAP requests can be abused to read local files or make server-side HTTP requests to arbitrary URLs. An attacker can use this to...

CVE-2026-54342 TLS Certificate Verification Disabled on CXF Transport Clients in epa4all

In epa4all, prior to version 2026-05-20, an attacker on the network path between epa4all and any backend ePA Aktensystem, Konnektor, IDP, TSS can present a self-signed TLS certificate and intercept the connection. For non-VAU connections Konnektor, IDP, this allows direct read and modification of...

CVE-2026-54342 TLS Certificate Verification Disabled on CXF Transport Clients in epa4all

In epa4all, prior to version 2026-05-20, an attacker on the network path between epa4all and any backend ePA Aktensystem, Konnektor, IDP, TSS can present a self-signed TLS certificate and intercept the connection. For non-VAU connections Konnektor, IDP, this allows direct read and modification of...

CVE-2026-54342

The CVE affects epa4all prior to 2026-05-20, where TLS certificate verification is disabled on CXF transport clients. A network attacker can intercept connections between epa4all and backends (ePA Aktensystem, Konnektor, IDP, TSS) by presenting a self-signed certificate. For non-VAU backends (Kon...

CVE-2026-54342 TLS Certificate Verification Disabled on CXF Transport Clients in epa4all

In epa4all, prior to version 2026-05-20, an attacker on the network path between epa4all and any backend ePA Aktensystem, Konnektor, IDP, TSS can present a self-signed TLS certificate and intercept the connection. For non-VAU connections Konnektor, IDP, this allows direct read and modification of...

The vulnerabilities of the components camel-knative-http, camel-cxf-rest, and camel-cxf-transport from the Apache Camel framework allow attackers to execute arbitrary code or gain unauthorized access during write operations.

The vulnerability of the camel-knative-http, camel-cxf-rest, and camel-cxf-transport components of the Apache Camel framework is related to deficiencies in the mechanism for processing registry-dependent data. Exploiting this vulnerability allows an attacker to execute arbitrary code or gain...

apache-cxf: org.apache.cxf/cxf-rt-rs-security-oauth2: Apache CXF: Token Confusion/Routing attacks due to improper validation of JWT audience claims

A flaw was found in Apache CXF. The JwtAccessTokenValidator class fails to properly validate the 'aud' Audience claims within incoming JSON Web Token JWT access tokens. This vulnerability allows an attacker to reuse a JWT, originally intended for one resource server, against a different resource...

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...
