CVE-2025-30753Network attack vector

Authenticated denial of service via undisclosed Core flaw

Published Jul 15, 2025 · Updated Jul 16, 2025

Denial of service in Oracle WebLogic Server Core 12.2.1.4.0, 14.1.1.0.0, and 14.1.2.0.0 allows remote authenticated users to hang or crash servers. Oracle has not disclosed the specific Core locus or the operation on untrusted HTTP input that triggers the availability failure. A low-privileged account and network access to HTTP are required; successful exploitation interrupts availability without data exposure or modification.
