"The version of Spring Framework installed on the remote host is 5.3.x prior to 5.3.49. It is, therefore, affected by
multiple vulnerabilities:

  - Spring WebFlux applications may be vulnerable to a security bypass when using the Kotlin Router DSL.
    (CVE-2026-41847)

  - An integer overflow vulnerability exists in the evaluation logic of the Spring Expression Language (SpEL). An
    attacker can exploit this by supplying a specially crafted SpEL expression that triggers excessive resource
    consumption, resulting in a Denial of Service (DoS). (CVE-2026-41849)

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