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

  - jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data
    Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply
    nested JSON if (and only if) the service reads deeply nested (1000s of levels) JSON as JsonNode
    (ObjectMapper.readTree()) and writes out same (or modifided) node using JsonNode.toString(). This can
    consume significant amount of resources with concurrent relatively small requests (1000 nested arrays is
    2kB). This vulnerability is fixed in 2.14.0. (CVE-2026-50193)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1949 advisory.

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:76130 advisory.

    Red Hat Single Sign-On 7.6 is a standalone server, based on the Keycloak project, that provides     authentication and standards-based single sign-on capabilities for web and mobile applications.

    This release of Red Hat Single Sign-On 7.6.13 on RHEL 9 serves as a replacement for Red Hat Single Sign-On     7.6.12, and includes bug fixes and enhancements, which are documented in the Release Notes document linked     to in the References.

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

  - jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data     Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply     nested JSON if (and only if) the service reads deeply nested (1000s of levels) JSON as JsonNode     (ObjectMapper.readTree()) and writes out same (or modifided) node using JsonNode.toString(). This can     consume significant amount of resources with concurrent relatively small requests (1000 nested arrays is     2kB). This vulnerability is fixed in 2.14.0. (CVE-2026-50193)

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