"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the TSSA-2026:0824 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2026-54513:
    jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data
    Processor. From 2.10.0 until 2.18.8, 2.21.4, and 3.1.4,
    BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray() allowlists any array type based only on
    clazz.isArray(), without validating the array's component (element) type against the configured allowlist.
    A PTV built with allowIfSubTypeIsArray() plus an explicit concrete-type allowlist therefore still permits
    EvilType[] even though EvilType is not allowlisted. When Jackson deserializes the elements and no per-
    element type IDs are present, it instantiates the component type directly with no further PTV check,
    bypassing the allowlist. This vulnerability is fixed in 2.18.8, 2.21.4, and 3.1.4.

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

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