Apache CXF < 3.6.12 / 4.x < 4.1.8 / 4.2.x < 4.2.3 Multiple Vulnerabilities

critical Nessus Plugin ID 335183

Synopsis

Apache CXF is affected by multiple vulnerabilities.

Description

The version of Apache CXF installed on the remote host is prior to 3.6.12, or 4.x prior to 4.1.8, or 4.2.x prior to 4.2.3. It is, therefore, affected by multiple vulnerabilities, including:

- The JMS transport deserializes the body of any inbound JMS ObjectMessage using native Java deserialization, with no type restrictions in place. An attacker able to place a message on the service's JMS destination can submit a malicious serialized object, leading to denial of service or remote code execution. (CVE-2026-66909)

- In DefaultEncryptingCodeDataProvider, a captured authorization code can be redeemed an unlimited number of times due to a flaw in the implementation of the removeCodeGrant functionality, violating the RFC requirement that the authorization code must not be used more than once. (CVE-2026-68079)

- The OAuth2 Dynamic Client Registration endpoint accepts and stores the scope value supplied in the client registration request verbatim, without validating it against an AS-defined allowlist. This could lead to a client self-assigning privileged scopes at registration time. (CVE-2026-61466)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache CXF version 3.6.12, 4.1.8, or 4.2.3 or later.
