This vulnerability allows a remote attacker to bypass security controls by exploiting an issue in how properties are handled when both @JsonProperty (for renaming) and @JsonIgnore (for ignoring) annotations are used. By supplying a specially crafted JSON key, an attacker can directly write to a private data field, circumventing the intended security restrictions and potentially leading to unexpected data modification.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Cryostat 4, OpenShift Developer Tools and Services, OpenShift Serverless, Red Hat AMQ Broker 7, Red Hat AMQ Clients, Red Hat Ansible Automation Platform 2, … · no fix planned: Cryostat 4, OpenShift Developer Tools and Services, OpenShift Serverless, Red Hat AMQ Broker 7, … · updated 2026-09-13 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-54516.json)\n\n**jackson-databind: jackson-databind: Security bypass due to improper handling of renamed properties** — rated Moderate by Red Hat.
