CVE-2026-54517

A flaw was found in jackson-databind. A remote attacker can exploit this vulnerability due to an issue in how active-view (@JsonView) filters are applied. Specifically, setterless collections annotated with a restricted @JsonView can be populated from attacker-controlled JSON even when the active view is configured to exclude them. This can lead to information disclosure, allowing an attacker to access data that should otherwise be restricted.

Moderate: A flaw in jackson-databind allows for information disclosure and an access-control bypass. This occurs because the @JsonView filter, intended to restrict data visibility, is not correctly applied to setterless collection and map properties during deserialization. An attacker could exploit this to populate view-restricted properties from untrusted JSON, potentially accessing sensitive data that should be excluded by the active view.
