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." Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-500570 advisory.

    ovirt-engine-wildfly     [24.0.1-4]
    - Update all bundled CXF release artifacts to 3.6.13

    ovirt-engine-wildfly-overlay     [24.0.1-4]
    - Require WildFly 24.0.1-4 with the CXF 3.6.13 update

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-500571 advisory.

    ovirt-engine-wildfly     [24.0.1-4]
    - Update all bundled CXF release artifacts to 3.6.13

    ovirt-engine-wildfly-overlay     [24.0.1-4]
    - Require WildFly 24.0.1-4 with the CXF 3.6.13 update

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

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.
