Improperly Implemented Security Check for Standard

Overview org.apache.cxf:cxf-rt-rs-security-oauth2 is a services framework. Affected versions of this package are vulnerable to Improperly Implemented Security Check for Standard due to a logic error in the OAuthRequestFilter request handler. An attacker can bypass intended IP address restrictions...

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-2026-50632

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-2026-50623

An authentication bypass vulnerability exists in the OAuth2 TokenIntrospectionService in Apache CXF. Due to a missing 'throw' keyword in the security context check, the introspection endpoint /services/oauth2/introspect can be accessed by any unauthenticated network attacker. However note that th...

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, which fix this issue by...

CVE-2026-50632

CVE-2026-50632 : Apache CXF exposes a JNDI Injection vulnerability in the JMSConfigFactory. The issue arises when untrusted users configure JMS, potentially allowing code execution. Affected versions are addressed by upgrades to 4.2.2 or 4.1.7. The NVD/CVEs and related feeds document this as a co...

CVE-2026-50629 Apache CXF: OAuth2: Log Injection via Unsanitized Client Identifier

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-2026-50628 Apache CXF: OAuth2: Inverted IP Binding Check Defeats Security Control

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-2026-49875 Apache CXF: XML External Entity (XXE) Injection in W3CMultiSchemaFactory and EndpointReferenceUtils

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, which fix this issue...
