CVE-2026-54517: CWE-863: Incorrect Authorization in FasterXML jackson-databind
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.
AI Analysis
Technical Summary
In jackson-databind versions >=2.21.0 <2.21.4 and >=3.1.0 <3.1.4, the active-view (@JsonView) filter was applied only to creator properties during deserialization in BeanDeserializer._deserializeUsingPropertyBased. The regular property-buffering branch did not check property visibility against the active view. A change causing SetterlessProperty.isMerging() to return true routed setterless Collection/Map properties through this unguarded path, allowing such properties annotated with restricted @JsonView to be populated from attacker JSON even when the active view excludes them. This incorrect authorization flaw is addressed in versions 2.21.4 and 3.1.4.
Potential Impact
An attacker can bypass @JsonView restrictions on setterless Collection/Map properties during JSON deserialization, potentially causing unauthorized data to be set from attacker-controlled input. This leads to an integrity impact without confidentiality or availability effects. The CVSS score is 5.3 (medium severity), reflecting limited impact with no required privileges or user interaction.
Mitigation Recommendations
This vulnerability is fixed in jackson-databind versions 2.21.4 and 3.1.4. Users should upgrade to at least these versions to remediate the issue. No other mitigation or workaround is indicated.
