Description
This security bulletin contains information about 2 vulnerabilities.
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.
2) Incorrect authorization (CVE-ID: CVE-2026-59889)
CWE-ID: CWE-863 - Incorrect Authorization
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to escalate privileges.
The vulnerability exists due to improper access control in UnwrappedPropertyHandler.processUnwrapped() when deserializing @JsonUnwrapped container properties under a less-privileged active view. A remote user can supply crafted JSON values for a property annotated with both @JsonView and @JsonUnwrapped to escalate privileges.
This affects the write-side authorization behavior of @JsonView during deserialization, including merge and builder-based deserialization paths.
