Description

This security bulletin contains information about 1 vulnerability.


1) Improperly Controlled Modification of Dynamically-Determined Object Attributes (CVE-ID: CVE-2026-59888)

CWE-ID: CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to modify dynamically determined object attributes.

The vulnerability exists due to improper control of dynamically determined object attributes in jackson-databind record deserialization when applying a PropertyNamingStrategy to `@JsonIgnore`-annotated Record properties. A remote attacker can supply a specially crafted JSON key to modify dynamically determined object attributes.

This issue affects Java Records during deserialization when a naming strategy is used and `@JsonIgnore` is relied on to prevent a component from being set from input.
