Description

This security bulletin contains information about 3 vulnerabilities.

1) Improperly Controlled Modification of Dynamically-Determined Object Attributes (CVE-ID: CVE-2026-54515)

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:N/VI:L/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to modify otherwise ignored object attributes.

The vulnerability exists due to improper control of dynamically determined object attributes in BeanDeserializerBase.createContextual() when processing case-insensitive deserialization with per-property @JsonIgnoreProperties exclusions. A remote attacker can send crafted JSON input to modify otherwise ignored object attributes.

Only applications that enable case-insensitive property matching and rely on per-property @JsonIgnoreProperties to keep a field unwritable are vulnerable.

2) 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.

3) 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.
