CVE-2026-61227Network attack vector

Low-privileged unauthorized data access and modification

Published Aug 18, 2026 · Updated Aug 20, 2026

Access control flaw in Oracle WebCenter Portal 12.2.1.4.0 and 14.1.2.0.0 lets remote authenticated users read and modify data over HTTP. Oracle identifies the affected code only as the Runtime Tools component and has not disclosed the failing endpoint or authorization check, so the precise mechanism remains undisclosed. Exploitation requires low-privileged access and user interaction, and Oracle rates the resulting impact as broad data disclosure plus limited data modification with scope change.
