CVE-2026-61018Network attack vector

Unauthenticated application takeover

Published Aug 18, 2026 · Updated Aug 21, 2026

Unspecified vulnerability in Oracle WebCenter Sites 12.2.1.4.0 and 14.1.2.0.0 allows remote attackers to take over the server via HTTP. Oracle has not published the flaw's locus or the operation it performs on untrusted input; public Oracle and NVD records describe only an easily exploitable unauthenticated HTTP path to full compromise. No credentials or user interaction are required, so any internet- or intranet-reachable deployment running those supported versions warrants urgent triage for complete confidentiality, integrity, and availability loss.
