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, UnwrappedPropertyHandler.processUnwrappedCreatorProperties() replays buffered JSON into creator parameters but never consults prop.visibleInView(activeView). The normal property-based creator path gates creator properties on the active view, but this unwrapped-creator replay path bypasses that check, so a constructor parameter annotated with both @JsonView(AdminView.class) and @JsonUnwrapped is populated from attacker JSON even when a more restrictive view is active. This vulnerability is fixed in 2.21.4 and 3.1.4.

The remote Fedora 45 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-ddde3cf003 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,
    UnwrappedPropertyHandler.processUnwrappedCreatorProperties() replays buffered JSON into creator parameters
    but never consults prop.visibleInView(activeView). The normal property-based creator path gates creator
    properties on the active view, but this unwrapped-creator replay path bypasses that check, so a
    constructor parameter annotated with both @JsonView(AdminView.class) and @JsonUnwrapped is populated from
    attacker JSON even when a more restrictive view is active. This vulnerability is fixed in 2.21.4 and
    3.1.4. (CVE-2026-54518)

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