jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and 3.1.4, in BeanDeserializer._deserializeUsingPropertyBased, the active-view (@JsonView) filter was applied only to creator properties; the regular property-buffering branch performed no prop.visibleInView(activeView) check. A change making SetterlessProperty.isMerging() return true routed setterless Collection/Map properties through this unguarded path, so a setterless collection annotated with a restricted @JsonView is populated from attacker JSON even when the active view excludes it. This vulnerability is fixed in 2.21.4 and 3.1.4.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 0cb401f9-9f19-11f1-a655-3497f65b111b advisory.

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 2.21.0 until 2.21.4 and 3.1.4, in BeanDeserializer._deserializeUsingPropertyBased, the
    active-view (@JsonView) filter was applied only to creator properties; the regular property-buffering
    branch performed no prop.visibleInView(activeView) check. A change making SetterlessProperty.isMerging()
    return true routed setterless Collection/Map properties through this unguarded path, so a setterless
    collection annotated with a restricted @JsonView is populated from attacker JSON even when the active view
    excludes it. This vulnerability is fixed in 2.21.4 and 3.1.4. (CVE-2026-54517)

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