Missing Authentication for Critical Function

Overview org.apache.cxf:cxf-rt-rs-security-oauth2 is a services framework. Affected versions of this package are vulnerable to Missing Authentication for Critical Function due to a missing 'throw' keyword in the security context check within the TokenIntrospectionService method. An attacker can...

Allocation of Resources Without Limits or Throttling

Overview org.apache.cxf:cxf-core is an an open source services framework. CXF helps you build and develop services using frontend programming APIs, like JAX-WS and JAX-RS. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of...

Authentication Bypass by Alternate Name

Overview org.apache.cxf:cxf-rt-rs-security-oauth2 is a services framework. Affected versions of this package are vulnerable to Authentication Bypass by Alternate Name via the JwtAccessTokenValidator class. An attacker can gain unauthorized access to protected resources by replaying a JWT access...

Improper Validation of Specified Type of Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Type of Input in the DispatchMDBMessageListenerImpl method. An attacker can achieve arbitrary code execution by providing crafted values in the JCA deployment descriptor ra.xml or runtime activation...

Improper Validation of Specified Type of Input

Overview Affected versions of this package are vulnerable to Improper Validation of Specified Type of Input in the JMSConfigFactory method. An attacker can execute arbitrary code by supplying untrusted JMS configuration data. Remediation Upgrade org.apache.cxf:cxf-rt-transports-jms to version...

HTTP Response Splitting

Overview org.apache.cxf:cxf-rt-rs-security-oauth2 is a services framework. Affected versions of this package are vulnerable to HTTP Response Splitting via improper handling of the realm parameter in the construction of the WWW-Authenticate response header. An attacker can inject arbitrary HTTP...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview org.apache.cxf:cxf-rt-rs-security-oauth2 is a services framework. Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition due to a race condition in the AbstractOAuthDataProvider method when handling refresh tokens if the recycleRefreshTokens...

CVE-2026-50631

A race condition in AbstractOAuthDataProvider allows concurrent requests using the same Refresh Token to bypass single-use semantics and generate multiple valid Access Tokens, when 'recycleRefreshTokens' is set to false. A leaked refresh token can be replayed concurrently by multiple attackers or...

CVE-2026-50633

A JNDI Injection vulnerability has been discovered in Apache CXF's JCA integration module, which can allow for code execution, if an attacker is able to manipulate the JCA deployment descriptor ra.xml or runtime activation parameters. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or...

CVE-2026-50634

A vulnerability in Apache CXF's JwsJsonContainerRequestFilter can be exploited to cause CXF to process metadata that was not authenticated by the accepted signature. This can bypass the application's assumption that accepted Content-Type or protected HTTP-header metadata came from a verified...

CVE-2026-50645

There is no restriction on the amount of attachment headers that a message can contain when being deserialized by Apache CXF, which can lead to uncontrolled resource consumption or a denial of service attack. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this...

CVE-2026-50632

A further incomplete fix for a previous advisory CVE-2026-44417 Untrusted JMS configuration can lead to RCE for Apache CXF has been identified, which can allow code execution capabilities, if untrusted users are allowed to configure JMS for Apache CXF. Users are recommended to upgrade to versions...

CVE-2026-50628

A logic error in OAuthRequestFilter rejects legitimate requests originating from the bound IP address, while blindly allowing requests from any other IP address. Enabling this security feature inadvertently creates an inverse security check. Users are recommended to upgrade to versions 4.2.2 or...

CVE-2026-50627

The JwtAccessTokenValidator class in Apache CXF fails to validate the 'aud' Audience claims of incoming JWT access tokens. This allows a JWT issued for one Resource Server to be successfully replayed against a completely different Resource Server, leading to Token Confusion/Routing attacks. Users...

CVE-2026-49875

Apache CXF's EndpointReferenceUtils and W3CMultiSchemaFactory classes construct a SAXParserFactory without the necessary JAXP hardening configurations, enabling out-of-band OOB external entity resolution. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this issue...

CVE-2026-50629

The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files. Users are recommended to upgra...

CVE-2026-50645

CVE-2026-50645 affects Apache CXF during message deserialization, where there is no restriction on the number of attachment headers. This can enable uncontrolled resource consumption and a denial-of-service condition. The issue is mitigated by limiting attachments per message to a default maximum...

CVE-2026-50645 Apache CXF: No restriction on attachment headers per message

There is no restriction on the amount of attachment headers that a message can contain when being deserialized by Apache CXF, which can lead to uncontrolled resource consumption or a denial of service attack. Users are recommended to upgrade to versions 4.2.2 or 4.1.7 or 3.6.12, which fix this...

EUVD-2026-36403
