CVE-2026-46842Network attack vector

Unauthenticated modification of accessible data

Published May 28, 2026 · Updated May 28, 2026

Improper access control in Oracle REST Data Services 24.2.0 through 26.1.0 allows remote attackers to modify data via HTTPS. Oracle identifies the Core component but does not disclose the affected endpoint or the operation that fails to enforce access control. No credentials or user interaction are required; successful requests can update, insert, or delete some ORDS-accessible data without reading it or interrupting service.
