This vulnerability occurs in the data-binding functionality where properties intended to be ignored are incorrectly restored and become writable again. An attacker could potentially exploit this by providing input that modifies data through these supposedly ignored properties. This could lead to unintended changes in application data, impacting data integrity.\n\n## Vendor advisories\n\n- **RHSA-2026:67604** · Red Hat · fixed in: Red Hat JBoss EAP 7.4 ELS for RHEL 7 Server, Red Hat JBoss EAP 7.4 ELS for RHEL 8, Red Hat JBoss EAP 7.4 ELS for RHEL 9 · released 2026-09-15 · [advisory](https://access.redhat.com/errata/RHSA-2026:67604)\n- **Red Hat VEX** · Moderate · affected: Cryostat 4, OpenShift Developer Tools and Services, OpenShift Serverless, Red Hat AI Inference Server, Red Hat AMQ Broker 7, Red Hat AMQ Clients, … · no fix planned: Red Hat JBoss Enterprise Application Platform Expansion Pack, Cryostat 4, OpenShift Developer Tools and Services, OpenShift Serverless, … · updated 2026-09-15 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-54515.json)\n\n**jackson-databind: jackson-databind: Ignored properties can be unexpectedly modified** — rated Moderate by Red Hat.
