Vulnerability identifier: #VU139154

CSH Severity: Medium

CVSS v4: 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]

CVE-ID: CVE-2026-54517

CWE-ID: CWE-863

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to bypass access controls and modify view-restricted properties.

The vulnerability exists due to incorrect authorization in BeanDeserializer._deserializeUsingPropertyBased when deserializing property-based input with setterless collection or map creator properties. A remote attacker can send specially crafted JSON input to bypass access controls and modify view-restricted properties.

Only setterless collection or map properties annotated with a restricted @JsonView and processed under an active view are affected.
