A WebFlux application using functional endpoints and deployed with DispatcherServlet may be vulnerable to a header predicate bypass in a pre-flight request. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49 Spring Framework 5.2.5.RELEASE - 5.2.25.RELEASE

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A WebFlux application using functional endpoints and deployed with DispatcherServlet may be vulnerable to
    a header predicate bypass in a pre-flight request. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 -
    6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49
    Spring Framework 5.2.5.RELEASE - 5.2.25.RELEASE (CVE-2026-47892)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A WebFlux application using functional endpoints and deployed with DispatcherServlet may be vulnerable to     a header predicate bypass in a pre-flight request. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 -     6.2.19 Spring Framework 6.1.0 - 6.1.28 Spring Framework 6.0.0 - 6.0.30 Spring Framework 5.3.0 - 5.3.49     Spring Framework 5.2.5.RELEASE - 5.2.25.RELEASE (CVE-2026-47892)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Spring Framework installed on the remote host is 5.2.5 prior to 5.2.26, 5.3.x prior to 5.3.50, 6.0.x prior to 6.0.31, 6.1.x prior to 6.1.29, 6.2.x prior to 6.2.20, or 7.0.x prior to 7.0.8.1. It is, therefore, affected by a vulnerability:

  - A WebFlux application using functional endpoints and deployed with DispatcherServlet may be vulnerable to a header     predicate bypass in a pre-flight request. (CVE-2026-47892)

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