Incorrect authorization in jackson-databind - CVE-2026-54518

Vulnerability identifier: #VU139153

CSH Severity: Medium

CVSS v4: 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]

CVE-ID: CVE-2026-54518

CWE-ID: CWE-863

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to bypass write-side authorization restrictions and modify view-restricted creator parameters.

The vulnerability exists due to improper authorization in UnwrappedPropertyHandler.processUnwrappedCreatorProperties() when processing untrusted JSON input for unwrapped creator parameters. A remote attacker can supply crafted JSON data to bypass write-side authorization restrictions and modify view-restricted creator parameters.

This issue occurs when applications use @JsonView as a write-side authorization boundary together with constructor parameters annotated with both @JsonView and @JsonUnwrapped.
