Echo: com.fasterxml.jackson.core:jackson-databind: security update to 2.21.4tools.jackson.core:jackson-databind: security update to 3.1.4

medium Tenable Self-Hosted Container Security Plugin ID 464769

Description

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)

Solution

Update the com.fasterxml.jackson.core:jackson-databind library and its related packages to version 2.21.4 or later.
